feat(devvit): port to Devvit Web (autowikimod) (#79)

Ports `devvit/` from the classic `@devvit/public-api` scaffold to Devvit
Web as `autowikimod`, ahead of the Data API closing to unregistered apps
on 2027-01-12.

- `devvit.json` + Hono `/internal/*` server on `@devvit/web` 0.14.8,
built to `dist/server/index.cjs` with `@devvit/start`.
- Cron publish every 20 min. `onModAction` dropped: its payload carries
no reason text and the cron already reads the mod log.
- Renderer ported from `build_wiki_content`. FR-7 merges a removal with
its `addremovalreason`. FR-8 shows approvals only when they reverse a
Reddit/AutoModerator removal, looked up in a Redis hash keyed by target
id.
- Settings: wiki page (default `modlog-devvit` for side-by-side
cutover), days shown/kept (90), action list, anonymize (cannot be
disabled), ignored moderators. Menu: Publish now, Force rebuild, Test
connection.
- 42 Vitest tests (render, correlation, settings, Redis store on
`@devvit/test`, publish cycle). The golden parity test runs a fixture
through the unmodified Python publisher and requires byte-identical TS
output; CI regenerates the golden with uv and fails on drift.
- New `devvit.yml` workflow on the `hetzner` runner.

Not yet uploaded or playtested. Deliberate differences from Python and
the live-playtest list are in `devvit-migration/docs/STATUS.md`.

Supersedes #72 (public-api bump) since the classic package is removed.

 ## Status
 
-Scaffold stage: requirements + research + architecture complete; component modules (`storage`, `modlog`, `render`, `wiki`, `settings`, `menu`, `main`) written and type-checking clean. Not yet `devvit upload`-tested against a live test subreddit. See [`docs/STATUS.md`](docs/STATUS.md).
-
-This scaffold was produced by a multi-agent scrum (requirements → research → architecture → per-component implementation → scaffold). Treat the generated TypeScript as a reviewed starting point, not a shipped app — every Devvit API call should be validated in `devvit playtest` before publishing.
+Ported to Devvit Web; type-check, tests, build and Python parity pass offline. Awaiting upload and a live run on r/OpenSignups. See [`docs/STATUS.md`](docs/STATUS.md). `docs/01..04` describe the earlier classic-model design.
