Import and display MLIP v3 extras

[ModerRAS]

Summary

• accept MLIP v3 and import typed series extras without caching them as normal episodes
• persist extra metadata through Room schema 9 while keeping MLIP v1/v2 compatible
• show a separate playable extras section and isolate extras from episode counts, Bangumi sync, next playback, and continue watching

Verification

• ./gradlew test assembleDebug
• focused MLIP v1/v2/v3 importer, Room migration, poster grouping, resolver, and playback tests
• full lint still reports pre-existing API/opt-in findings under EarlyStartupDiagnostics.kt and PlayerScreen.kt; CI lint is configured continue-on-error

Warning

Review limit reached

@ModerRAS, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 45 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

This PR adds MLIP v3 series-extra import support, persists extra metadata through Room version 9, separates extras from normal episode flows, exposes extra episodes in anime details, and updates the app version from 1.1.0 to 1.2.0.

Changes

Series extras support

Layer / File(s)	Summary
Extra metadata persistence and migration repository-api/..., data/src/main/kotlin/com/miruplay/tv/data/..., data/schemas/..., app/src/main/..., data/src/test/..., app/src/test/...	MediaIndexEntry and Room index entities now store extra kind, ordinal, sort order, and duration. Room version 9 adds migration 8→9, schema coverage, wiring, and round-trip tests.
MLIP v3 extra import scanner/src/main/kotlin/..., scanner/src/test/kotlin/...	MLIP v3 validation requires the extra table and capability, parses and validates extra records, imports them into the index, reports counts, and tests invalid and compatible database variants.
Repository separation and projection repository-api/src/main/kotlin/com/miruplay/tv/repository/..., repository-api/src/test/kotlin/...	Extra entries are excluded from episode caches, lookup, playback, and poster counts, while toIndexedExtras projects ordered extra episodes and anime details expose de-duplicated extras.
Anime detail rendering ui-tv/src/main/kotlin/com/miruplay/tv/ui/detail/...	Extra episode progress is published separately and displayed in a 特典 section with EX badges and extra-specific titles.

- Around line 76-80: Update the merged extras pipeline in LibraryAnimeResolver
so the result of flatMap and distinctBy(Episode::id) is sorted using the
existing extra_kind/extra_sort_order comparator before returning. Add a test
covering extras from multiple related groups and verify the merged ordering.

In
`@repository-api/src/main/kotlin/com/miruplay/tv/repository/MediaIndexRepository.kt`:
- Around line 23-25: Update the episode/extra classification flow in
MediaIndexRepository to handle a null result from MediaExtraKind.fromValue
before any episode or extra helpers use extraKind. Ensure rows with unmapped
extra_kind values are excluded from normal episode counting and episode flows
rather than treated as episodes, while preserving existing behavior for mapped
values.
