- Add `@sofa/tsconfig` package with a shared `base.json` (target, lib, strict, moduleResolution, etc.) and migrate all packages/apps to `"extends": "@sofa/tsconfig/base.json"` to eliminate duplicated compiler options
- Move `display-status.ts` (and its `DisplayStatus` type + `getDisplayStatus` fn) from `@sofa/api` to `@sofa/core`; remove the `./display-status` export from `@sofa/api` and update all import sites in `discovery.ts` and `tracking.ts`
- Add `packages/core/test/display-status.test.ts`: 15 tests covering `ONGOING_TMDB_STATUSES` and all `getDisplayStatus` branches (movie, TV watchlist/in_progress/caught_up/completed, edge cases)
- Add `packages/i18n/vitest.config.ts` and two new test files: `date-buckets.test.ts` and `format.test.ts` covering date bucketing and locale formatting utilities
- Add `apps/public-api` (`@sofa/public-api`) — minimal Hono app
deployable to Vercel; `GET /v1/version` fetches the latest GitHub
release and returns `{ version, releaseUrl }` with a 15-minute
CDN cache (`s-maxage=900, stale-while-revalidate=3600`)
- Update `packages/core/src/update-check.ts` to call
`PUBLIC_API_URL/v1/version` instead of the GitHub API directly;
`PUBLIC_API_URL` defaults to `https://public-api.sofa.watch`
