Finish replay implementation

[diegurrio]

Summary

Completes the in-app Replay experience for the Android app. The app no longer depends on sharing a .ulg into it through Android intents. Instead it has an in-app library you import logs into, a recents shortcut on Home, and touch controls for playback on the renderer.

What's included

In-app log library (feature:replay)

• Import .ulg files with the system document picker (ACTION_OPEN_DOCUMENT). Each file is copied into app storage (filesDir/library/<id>.ulg) with metadata in Room, so playback works offline and keeps working even if the original file goes away.
• Recents list showing name, size, and import date. Long press a row to delete it (with a confirmation).
• Empty state with an "Open file" call to action.

Home recents peek

• The Home screen shows the three most recent flights below the mode cards. Tapping one plays it directly.

Touch transport overlay on the renderer

• Play/pause, drag to seek, and a speed control (0.5x / 1x / 2x / 4x), with current and total time.
• Driven from Compose through a small replay_* JNI control surface into the native engine. The bar lives in a dedicated full width overlay window so it composites above the GL surface and spans the screen edge to edge.

Renderer process isolation

• The native renderer (HawkeyeActivity) now runs in its own :renderer process and exits cleanly on teardown. This fixes a freeze (ANR) and a rotation crash that could occur after returning from a replay, and guarantees a clean start for every playback.

Cleanup

• Removed the old share/VIEW intent path (IntentRouterActivity, its intent filters, and the trampoline theme) now that importing happens in app.

Architecture

• Feature first modules following the project's MVI conventions: presentation (State/Action/Event/ViewModel plus a stateless Screen), domain contracts, and data implementations.
• Shared contracts (LibraryEntry, ReplayLibraryRepository) live in core:domain and the playback launch seam lives in core:presentation, so the feature modules stay decoupled.
• Room and KSP were added for the library metadata. The native side gained a thread safe control surface that the render loop applies each frame.

Testing

• 60 unit tests (ViewModels, repository coordination, file store and staging, formatters) and 8 instrumented tests (navigation and rotation across every screen, plus multi item library behavior).
• Verified on a Pixel 6 Pro: import, recents, playback with the transport controls, and returning to the shell.

Pull request overview

This PR replaces the inbound share/VIEW/SEND flow on Android with an in-app replay library (Room-backed metadata + on-disk payloads), adds a Compose touch transport overlay above the native renderer driven via a new JNI control surface, and surfaces recent flights on Home. The native HUD gains a show_transport flag so Android can suppress the built-in transport bar in favor of the overlay. The renderer (HawkeyeActivity) is moved into a separate :renderer process, and the dead IntentRouterActivity/ReplayViewModel/feature:replay:domain module are removed.

Changes:

• Add ReplayLibraryRepository in core:domain, Room+LibraryFileStore implementation in feature:replay:data, and Compose library + Home recents UIs.
• Add native replay_control (atomic request/snapshot bridge) and replay_jni so Kotlin NativeReplayController can pause/seek/speed the engine; Compose TransportRoot polls status at 10 Hz and renders in a TYPE_APPLICATION_PANEL window above raylib.
• Switch Android to run HawkeyeActivity in :renderer (Koin skipped there, hard-exit on destroy); HUD gets show_transport plumbed into layout and hud_bar_height for desktop/WASM compatibility.
