Relative hrefs in the built index.html ("manifest.webmanifest", "icon.svg")
resolve against the *document* URL, not the site root. Since this is an
SPA where every route serves the same shell, a route with more path
segments than the base path (e.g. /budget2.0/month/2026-09, which is
where the app's own catch-all route redirects on first load) resolved
these to a wrong, 404ing path — breaking the manifest and favicon, and
with them installability, on the app's default landing URL.
build.ts now rewrites both hrefs to be absolute (prefixed with basePath)
as part of the existing dist/index.html -> dist/404.html step, keeping
the two files byte-identical. src/index.html itself keeps the plain
relative hrefs unchanged, since the substitution only happens in the
built dist/ output.
Also fixes a pre-existing, previously-uncaught bug surfaced while
verifying the dev server: bun --hot src/index.ts 500'd on every request
because Bun's dev-server HTML bundler (unlike Bun.build) has no
equivalent of the `external` build option and always tries to resolve
<link> hrefs as module imports — manifest.webmanifest never existed as a
real file under src/, only as build.ts's generated dist/ output. Added
src/manifest.webmanifest as a small static placeholder so the dev server
can resolve it; the production build still ignores this file entirely
(external: ["*.webmanifest"] in build.ts) and writes its own generated
manifest, unaffected by this addition.

The precache list is generated from Bun.build's outputs, so hashed asset
names cannot drift. A waiting worker prompts to reload rather than
pinning the user to a stale build.
Two fixes beyond the brief: naming.entry changed from "[dir]/[name].[ext]"
to "[name].[ext]" because [dir] resolved to "src", putting index.html at
dist/src/index.html instead of the dist root; and external:
["*.webmanifest", "*.svg"] was added because Bun's HTML bundler otherwise
tries to resolve <link> hrefs as module imports, which fails outright for
the not-yet-generated manifest.webmanifest and would hash icon.svg,
breaking the fixed paths the manifest and service worker depend on.
happy-dom is registered per-file in src/ui/registerSw.test.ts only, not
as a global test preload, so src/domain/smoke.test.ts still guards the
domain layer's DOM-free invariant.
PNG icons (192px/512px) are not included — binary image generation isn't
available here; a human needs to add them for full Chrome installability.

bun init --react=shadcn, with the demo API routes removed since this app
has no backend. Adds project invariants to CLAUDE.md and a smoke test
proving the domain layer imports with no DOM.
