fix(ingest): support redesigned Blue Archive wiki event table

The Blue Archive Wiki (bluearchive.wiki/wiki/Events) redesigned its schedule, replacing the per-version MediaWiki tabber with a unified #eventtable displaying JP and Global periods side-by-side. - Parse #eventtable resolving GL Period, event titles, and article links from .event-region-gl, with fallback to .event-region-jp. - Maintain backwards compatibility with legacy tabber schedule format. - Add pinned fixture fixtures/ba/bawiki-events-2026-09-17 and tests. - Update snapshot, AGENTS.md, ARCHITECTURE.md, and INGESTION.md.

 exactly as the Fandom one does.

-Three things about that page are worth knowing before touching it, all of them ways to publish a
-confidently wrong date:
+The page was redesigned in September 2026 from a per-version tabber into a unified `#eventtable`
+schedule (`Preview | Event | JP Period | GL Period | Notes`). The parser supports both shapes. Key rules:

- **It states JP and Global in separate tabs, and the Japanese one runs four to nine months ahead.**
-  Same hazard as the CN column on `akwiki`, same answer: publish Global only. The tab's *nav button*
-  carries the id `tabber-Global_version-label` and sits above **both** panels, so a reader that slices
-  from the first id match reads the Japanese schedule while believing it read ours.
- **There are three Global tabs, not one** — the schedule, plus Mini-Event and Joint Firing Drill
-  further down, whose ids are the same name with `_2` and `_3`. The parser finds the schedule by its
-  `Name (EN)` header rather than by position, and `canParse` asserts that lookup, so a renamed tab or
-  column fails the run instead of quietly emptying the lane.
+- **Global is ours, Japanese runs four to nine months ahead.** In `#eventtable`, JP and GL periods
+  sit side-by-side; the parser resolves `GL Period`, and draws titles and links from `.event-region-gl`
+  (falling back to `.event-region-jp` if unlocalized). In the legacy tabber format, JP and Global sat in
+  separate panels, and the Global tab's nav button (`tabber-Global_version-label`) preceded both panels.
+- **Identify tables by their headers, not by position.** In `#eventtable`, column names (`Event`,
+  `GL Period`) identify the schedule. In the legacy tabber, `Name (EN)` distinguished the main schedule
+  from Mini-Event and Joint Firing Drill tabbers below. Both are asserted in `canParse`.
 - **The page states no time of day and no timezone anywhere.** The schedule's dates are bare
-  `YYYY-MM-DD`, which is honest day precision. Its five other tables (Mini-Event, Reward campaigns,
-  Attendance bonuses, Guide missions, Joint Firing Drill) *do* carry a wall clock — `08/12/2026 11:00`
-  — but name no zone for it, and **three of the five do not say which server they describe**. Those
-  are deliberately unparsed, and that second clause is the whole reason: a clock whose server is
-  unknown cannot even be labelled with a day, because you do not know whose day it is. Attendance
-  bonuses would be a real dailies source if a zone is ever stated. For the same reason `ba` has no
-  `resetOffsets`: Blue Archive Global does run one worldwide server, but nothing in this source says
-  on what clock.
+  `YYYY-MM-DD` (or `YYYY/MM/DD` in `datetime` elements), which is honest day precision. Its subsidiary
+  tables (Mini-Event, Reward campaigns, Attendance bonuses, Guide missions, Joint Firing Drill) *do*
+  carry a wall clock — `08/12/2026 11:00` — but name no zone for it, and **three of the five do not say

+  whose day it is. Attendance bonuses would be a real dailies source if a zone is ever stated. For the
+  same reason `ba` has no `resetOffsets`: Blue Archive Global does run one worldwide server, but nothing
+  in this source says on what clock.

  **This rule governs a clock with no known server, not a clock with no stated zone** — a
  distinction worth drawing precisely, because it was drawn the wrong way once. As first written it

 `bawiki` is the mirror image of `fandom`: same MediaWiki software, opposite conclusion about which
 surface to read. bluearchive.wiki is Miraheze, whose `robots.txt` disallows `/w/` and `/*?action=`,
 so the API is closed and the rendered `/wiki/Events` page is what `*` is allowed — and it serves our
-own `User-Agent` a `200`. Three page facts drive the parser (all three in AGENTS.md § Blue Archive):
+own `User-Agent` a `200`. The parser handles both the redesigned schedule table (`#eventtable`,
+shipped in September 2026) and the legacy version tabber format:

- **JP and Global are separate tabs, months apart**, so only Global is published — the `akwiki`
-  hazard. The Global tab's nav *button* precedes both panels, so slicing from the first matching id
-  reads the Japanese schedule.
- **Three tabs are named Global**, the schedule plus Mini-Event and Joint Firing Drill. The schedule
-  is identified by its `Name (EN)` header rather than by position, and `canParse` runs the same
-  lookup so a rename fails the run rather than emptying the lane.
- **Nothing on the page states a time of day or a timezone.** The schedule's bare ISO dates are day
-  precision; the five tables that do carry a wall clock name no zone for it and are left unparsed
-  rather than read as UTC.
+- **Redesigned schedule (`#eventtable`)**: A unified table (`Preview | Event | JP Period | GL Period | Notes`)
+  plots both releases side-by-side. The parser resolves columns by name, reads English titles and links
+  from `.event-region-gl` (falling back to JP if unlocalized), extracts day-precision dates from `GL Period`
+  spans, and maps release badges (`data-release="rerun"`) and Notes to event types.
+- **Legacy tabber format**: Identifies the schedule panel inside `<article id="tabber-Global_version">`
+  by its `Name (EN)` column header rather than by position, fencing out the Japanese panel and the
+  undated Mini-Event / Joint Firing Drill tabbers further down.
+- **Nothing on the page states a time of day or a timezone.** Boundaries are bare `YYYY-MM-DD` (or formatted
+  `YYYY/MM/DD`), so all boundaries are parsed at day precision. The subsidiary tables that carry wall
+  clocks state no timezone and are left unparsed rather than read as UTC.

 `akwiki` shares a host family with `wikigg` and nothing else — arknights.wiki.gg has no `mp-event`
 cards, so the two are separate modules rather than one parser with a branch. Two things about that
