Android picture-in-picture, and fix three dead Android config files 1fa5aa46f9

Add PiP for native (ExoPlayer) video on Android. Video renders into a
SurfaceView behind the WebView, so PiP is driven by the Activity shrinking
into a floating window rather than the HTML5 PiP API (which WebKitGTK does
not implement, hence Android-only).

- PictureInPictureManager.kt: enter PiP with the video's aspect ratio
  (clamped to the 1:2.39-2.39:1 range Android accepts, outside which it
  throws), plus a play/pause RemoteAction. Hides the WebView while in PiP -
  it is opaque and sits above the surface, so it would otherwise occlude the
  video entirely - and re-fits the surface on exit.
- MainActivity.kt: onUserLeaveHint auto-PiP, onPictureInPictureModeChanged,
  and an AndroidPictureInPicture JS interface following the existing
  AndroidAudioFocus pattern.
- pictureInPicture.ts + VideoPlayer.svelte: PiP button, rendered only when
  the native bridge reports support.
- proguard: keep rules for @JavascriptInterface methods, which are only
  referenced from JS and would be stripped in minified release builds.

Casting needs no special handling: canEnterPip() checks natively that a
local video surface is attached and playing, which a remote session lacks.

While wiring the manifest, found that three tracked files under
src-tauri/android/ were never reaching any build. Gradle reads only
gen/android/app/src/main/, and sync-android-sources.sh did not copy them:

- src/main/AndroidManifest.xml was a partial <application> fragment written
  as if Tauri merged it. It does not - there is no manifest-merger hook
  here, so its hardwareAccelerated flag never reached an APK. Promoted to
  the complete authoritative manifest (folding in that flag) and synced.
- src/main/res/values/themes.xml (transparent status bar, fitsSystemWindows)
  was never copied; the sync only globbed mipmap-*. Now synced.
- build.gradle.kts was a leftover com.android.library module config with
  stale media3 1.5.1 deps. The live deps are in app/build.gradle.kts at
  1.5.0. Deleted.

Verified: merged manifest now carries hardwareAccelerated,
supportsPictureInPicture, resizeableActivity and the density configChange;
themes.xml compiles into merged resources; Kotlin builds warning-free;
svelte-check clean; 537 frontend tests pass.

Not verified: PiP behaviour on a device, and the release keep rules against
a minified build. assembleUniversalDebug cannot complete in this
environment - the Rust step wants a dev-server addr file that only exists
under `tauri android dev`.

Bump version to 0.0.16 027054a200

Needed to deploy over the CI-installed build on device: CI derives
versionCode as 1000 + major*10000 + minor*100 + patch, so the field is
already at 1000, while a local `tauri android build` writes the raw
patch number (15) and is rejected as a downgrade.

Cargo.toml is versioned independently (0.1.0) and is left alone.

Note: local builds still emit the raw code (16) - only CI applies the
1000+ formula, so deploying to a device with a CI build installed needs
gen/android/app/tauri.properties patched after Tauri regenerates it.

docs: add mdBook docs-site, publish workflow, and release-notes tooling 4e6ab017d4

Add a docs-site (mdBook) with a Gitea publish-docs workflow, a
release-notes generator script (release:notes) that turns a commit
range's TRACES into grouped notes, the background-audio feature spec,
and CLAUDE.md. Ignore docs-site build artifacts.

Background-audio handoff for video + repository/player refactor 3fbf6afdbc

Hand video playback off to a native audio-only stream when the app is
backgrounded or locked, with no on-device video decode (UR-040). Adds
player_enter/exit_background_audio commands, an audio-only stream URL
for video items across the repository layer, and the frontend handoff
state machine wired into VideoPlayer. Includes accompanying
repository/offline/player refactoring and regenerates the traceability
matrix.

fix resuming video playback after background audio only mode.
