mega: fix nil pointer panic when login with session keys fails - fixes #9232

When LoginWithKeys failed (e.g. after clearing Mega trash or with a stale session), the error was silently ignored and only logged at debug level. This left the filesystem uninitialized so GetRoot() returned nil, causing a nil pointer dereference panic in findDir. This returns the login error instead of swallowing it, and adds a nil check for GetRoot() in findRoot, and adds defensive nil node checks in findDir and findObject.

 <!--
-Put `Fixes #1234` here if this closes an issue, or `#1234` to link without closing.
-
-IMPORTANT: Anything beyond a trivial fix (typo, doc tweak, small obvious bug fix)
-should be discussed and agreed in an issue BEFORE you open a pull request.
-Pull requests for larger changes that have not been discussed in an issue first
-may be closed. This saves everyone's time if the change needs a different approach

-#### For new or changed backends
+#### Was the change discussed in an issue or in the forum before?

 <!--
-Backend pull requests are often sent without the integration tests having been run.
-We cannot merge a backend change until it passes the integration tests.
-
-To be merged, a backend change REQUIRES:
-  1. A clean run of `go run ./fstest/test_all -backends <remote>` (summarise the
-     result below or paste a screenshot of the test_all output in the web browser).
-  2. A test account so the maintainers can run the integration tests daily against
-     the backend on the integration test server.
-
-If the tests aren't quite passing yet and you need help getting them
-to pass, then submit the PR and we can help getting you over the line.
-
-See https://github.com/rclone/rclone/blob/master/CONTRIBUTING.md#writing-a-new-backend

-## Project Overview
-
-Rclone is a command-line program to sync files and directories to and from cloud storage providers. It's written in Go and supports 70+ backends (cloud storage systems). Think "rsync for cloud storage".
-
-## General Notes
-
-**We take backwards compatibility very seriously.** PRs should not change the observable behaviour of existing commands, flags or rc API without very good reason. Rclone does not try to preserve a stable Go API but try not to change it gratuitously.
-
-Rclone operates with a lot of different backends, so **compatibility is key**. It is the backend integration tests which guarantee that compatibility. Changes should consider both known and unknown backends and should take care not to break functionality of existing installations.
-
-The core parts of rclone under `fs` and `vfs` need to work with all backends and **backend specific hacks won't be merged**. Fixes likely need to go in the relevant backend or if new behaviour is really needed, a new Feature flag needs to be added.
-
-**Changes should be kept to the minimum.** Work hard to make the most elegant, smallest change you can. Do not refactor or re-order code unless necessary as this makes review more challenging. Re-use existing test scaffolding, existing or library routines (e.g. `lib`) where possible.
-
-Make sure added tests **actually test the code you have written** and test the intention behind the change. If you are fixing a problem, write the tests first to reproduce the problem before starting on the fix.
-
-Tests in `fs/operations`, `fs/sync`, `cmd/bisync`, `cmd/gitannex` and `vfs` (the definitive list is in `fstest/test_all/config.yaml`) are run on the integration test machine against **all** the backends, so they **must be prepared to run on backends with limited functionality**. Ideally tests, or parts of tests, should be skipped using the `Fs.Features()` flags on backends which can't support them.
-
-## Build and Test Commands
-
-```bash
-# Build rclone (simple)
-go build
-
-# Build with version info (preferred)
-make
-
-# Run all unit tests (no cloud credentials needed)
-make quicktest
-# or equivalently:
-RCLONE_CONFIG="/notfound" go test ./...
-
-# Run tests for a specific package
-cd backend/memory && go test -v
-# or from root:
-go test -v ./backend/memory/
-
-# Run a single test
-go test -v -run TestIntegration/FsCheckWrap ./backend/memory/
-
-# Run tests with race detector
-make racequicktest
-
-# Lint (requires golangci-lint)
-golangci-lint run ./...
-
-# Run backend integration tests (requires configured TestRemote remote)
-cd backend/drive && go test -v
-# Run sync/operations integration tests against a remote
-cd fs/sync && go test -v -remote TestDrive:
-cd fs/operations && go test -v -remote TestDrive:
-
-# Run integration tests via test framework
-go run ./fstest/test_all -backends drive
-```
-
-## Architecture
-
-### Entry Point and Plugin Registration
-
-`rclone.go` is the main entry point. It imports `backend/all` and `cmd/all` which use Go's `init()` pattern to register all backends and commands. Each backend calls `fs.Register()` with a `fs.RegInfo` struct during init.
-
-### Core Interfaces (`fs/`)
-
-The `fs` package defines the core abstractions:
- **`fs.Fs`** (`fs/types.go`): The filesystem interface every backend must implement (List, NewObject, Put, Mkdir, Rmdir).
- **`fs.Object`** (`fs/types.go`): Interface for a file/object (Open, Update, Remove, SetModTime).
- **`fs.Features`** (`fs/features.go`): Optional capabilities a backend can declare (Purge, Copy, Move, DirMove, etc.). Backends set function pointers for operations they support; nil means not supported.
- **`fs.RegInfo`** (`fs/registry.go`): Registration metadata for a backend including its name, config options, and NewFs constructor.
-
-### Backend Structure (`backend/`)
-
-Each backend is a single Go package (e.g., `backend/s3/`, `backend/drive/`). Key conventions:
- Main implementation in a single file (e.g., `s3.go`) - **do not** split into `fs.go`/`object.go`.
- API types go in a separate `api/types.go` file.
- Test file (e.g., `s3_test.go`) uses `fstests.Run()` from `fstest/fstests` for standardized integration tests.
- Register in `backend/all/all.go` via blank import.
- HTTP-based backends should use `lib/rest` for HTTP calls and `fs/fshttp` for the HTTP client.
- Use `lib/dircache` for directory-ID-based remotes, `lib/oauthutil` for OAuth, `lib/pacer` for rate limiting.
-
-### Command Structure (`cmd/`)
-
-Each command is a package under `cmd/` registered in `cmd/all/all.go` via blank import. Commands use cobra via `cmd.Main()`.
-
-### Key Subsystems
-
- **`fs/operations/`**: Core file operations (Copy, Move, Delete, etc.)
- **`fs/sync/`**: Directory sync logic
- **`fs/march/`**: Parallel directory tree walker used by sync
- **`fs/filter/`**: Include/exclude filtering
- **`fs/accounting/`**: Transfer statistics and bandwidth limiting
- **`fs/config/`**: Configuration file management
- **`vfs/`**: Virtual filesystem layer (used by mount, serve)
- **`librclone/`**: C-compatible library interface for embedding rclone
- **`fstest/`**: Integration test framework; `fstest/fstests/` has the generic backend test suite
-
-## Commit Message Convention
-
-Prefix with the directory of the change, then a colon: `drive: add team drive support - fixes #885`. For cross-cutting changes use a broader prefix like `fs` or `operations`.
-
-Make the first line of your commit message a summary of the change that a user (not a developer) of rclone would like to read. So write `drive: fix server side copy of big files` instead of `drive: no longer set the MimeType in Move or Copy`. This is important because these lines go into the change log which is read by users.
-
-## Code Commenting Style
-
-Comments describe the code as it is now, for a future reader who has no knowledge of the change that introduced it.
-
-Every exported type, function, field, and constant has a **godoc comment** that starts with its name and is phrased as a present-tense statement of what it is or does (`// Mkdir makes the directory (container, bucket)`)
-
-**Document the contract** callers need - preconditions, what's returned, which sentinel errors are returned and when, and any "shouldn't return an error if it already exists" style caveats - rather than the implementation.
-
-**Keep comments terse**: a single line for most things, with extra paragraphs (separated by blank `//` lines) reserved for genuine subtlety.
-
-Inline comments inside function bodies should **explain why** - a non-obvious API quirk, a workaround, a gotcha, or an ordering constraint - and may cite an external reference (forum thread, vendor docs, RFC) when that's what makes the behaviour non-obvious; skip comments that merely restate what the code plainly does.
-
-Use `FIXME` and `TODO` for known shortcomings.
-
-**Do not write comments that narrate the change itself** or compare against the previous behaviour (no "now we also handle...", "changed to...", "previously this returned...", or references to bug/PR numbers in the code) - that context belongs in the commit message, not in source that will outlive the change.
-
-Code comments should only refer to **current** behaviour - and shouldn't describe behaviour that is trivially deducible from reading the code.
-
-## Linting Configuration
-
-Uses golangci-lint v2 with config in `.golangci.yml`. Enabled linters: errcheck, govet, ineffassign, staticcheck, unused, gocritic, misspell, revive, unconvert. The `goimports` formatter is also enabled.
-
-## Documentation
-
- Backend option docs come from `Help:` fields in the Go source Options structs, not from markdown files.
- Command docs are in the command source code (e.g., `cmd/ls/ls.go`).
- Don't commit autogenerated doc changes from `make backenddocs` or `make commanddocs`.
- Website docs are in `docs/content/` as markdown, built with Hugo (`make serve` to preview).
-
-## Fork Workflow
-
-This fork carries agent tooling that upstream does not. Never include `docs/specs/`, `docs/plans/`, `docs/{ARCHITECTURE,DECISIONS,TODO,PERMISSIONS}.md`, `GEMINI.md`, `.claude/`, `.codex/`, `.gemini/` or this section in a PR to rclone/rclone.
-
- Required skill: `superpowers` - check at session start, install if missing. There is no product UI here, so `impeccable` is not needed.
- Specs go in `docs/specs/NNN-slug.md` (permanent). Plans go in `docs/plans/NNN-slug.md` and are removed with `git rm` before merge. This overrides the superpowers default paths.
- Paused or in-flight work is listed under "Now" in `docs/TODO.md` with the handoff to read first.
- Non-trivial work: brainstorm → spec → plan → TDD → review. For trivial fixes say "trivial, skipping spec" and proceed.
- Log things noticed but deliberately not fixed in `docs/TODO.md`, record decisions in `docs/DECISIONS.md`, and keep `docs/ARCHITECTURE.md` in step with structural changes - in the same commit as the code.
- `docs/PERMISSIONS.md` is the source for the `.claude/`, `.codex/` and `.gemini/` permission files - change them together.
- Never push, force-push or commit directly to `master`. Ask before adding or upgrading a dependency (`go get`, `go mod tidy`).
- Done means run in this session and seen passing: `go build`, `go test` on the touched packages, and `golangci-lint run` on them.

 - **Remember** we have >50 backends to maintain so keeping them as similar as
  possible to each other is a high priority!

-### Managing memory
-
-Use rclone's memory pool for upload buffers rather than allocating them
-yourself. This will enable `--max-buffer-memory` and `--use-mmap` and will make
-rclone's memory usage smaller.
-
- If the provider supports multipart or parallel chunk uploads, implement
-  [fs.OpenChunkWriter](https://pkg.go.dev/github.com/rclone/rclone/fs#OpenChunkWriter)
-  and drive it with
-  [multipart.UploadMultipart](https://pkg.go.dev/github.com/rclone/rclone/lib/multipart#UploadMultipart).
-  This gives you pooled chunk buffers, concurrency, retries and
-  `--multi-thread-streams` support for free. See s3/b2 backends for examples.
- If you must buffer data yourself take the buffer from the global pool with
-  [multipart.NewRW](https://pkg.go.dev/github.com/rclone/rclone/lib/multipart#NewRW)
-  and fill it with `io.CopyN`. The `pool.RW` is seekable so the same buffer can
-  be rewound for a retry.
- When using a pooled buffer `Close()` it on all paths so its pages go back to
-  the pool, `Seek(0, io.SeekStart)` inside the retry closure before each
-  attempt, set the request's `ContentLength` explicitly, and if the buffer
-  reaches `http.NewRequest` or an SDK without going through `lib/rest`, wrap it
-  in [readers.NoCloser](https://pkg.go.dev/github.com/rclone/rclone/lib/readers#NoCloser)
-  so the transport can't close it and free its pages before the retry.
-
 ### Unit tests

 - Create a config entry called `TestRemote` for the unit tests to use
 - Create a `backend/remote/remote_test.go` - copy and adjust your example remote
- If your backend does chunked uploads, set `ChunkedUpload` in the
-  `fstests.Opt` and implement `SetUploadChunkSize` (and `SetUploadCutoff`)
-  on your `Fs` in the test file so the `FsPutChunked`, `FsPutShortEOF` and
