Implement on-device iOS text-to-speech using AVSpeechSynthesizer,
mirroring the Android native TextToSpeech plugin so the shared
NativeTTSClient drives both platforms through the same command and
tts_events contract.
- Swift NativeTTSPlugin: speak/stop/pause/resume/rate/pitch/voice and
voice enumeration, with region-disambiguated duplicate voice names and
a small preUtteranceDelay to avoid first-word clipping.
- Enable the native TTS client on iOS in TTSController.
- Make TTS teardown resilient: reset UI state up front and tear down the
controller, media session, and background audio in parallel so a slow
native shutdown can never leave the TTS icon or lock-screen session
stuck on.
- Keep iOS on navigator.mediaSession for the lock screen (Android uses
the native foreground service), which restores the Edge TTS cover and
current-sentence metadata.

Backports the Android ANR/stability fixes from the julianshen fork,
adapted to upstream — notably preserving the cold-start shared-intent
replay queue and the #4559 dictionary-dispatch logic, neither of which
the fork kept.
- NativeBridgePlugin: run blocking @Command I/O (copy_uri_to_path,
install_package, get_sys_fonts_list, and show_lookup_popover's
queryIntentActivities) on Dispatchers.IO via a Main-dispatched
pluginScope; startActivity hops back to Main; resolves are
isActive-guarded; onDestroy cancels the scope and clears the static
instance; the system-font scan is cached (@Volatile). The cold-start
shared-intent queue (emitOrQueue / registerListener) is left intact.
- MediaPlaybackService: unmarshal the artwork Bitmap off the main thread
(serviceScope + Dispatchers.Default), isActive-guarded; cancel the
scope in onDestroy.
- ClipUrlController: hold the Activity via WeakReference and check
isFinishing/isDestroyed before presenting, to avoid leaking the
Activity/WebView during the up-to-30s clip window.
- MainActivity (#3297): on Android 14+ the window can gain focus before
the WebView paints its first frame, leaving a blank screen. Force one
repaint when both the window has focus and the WebView exists
(whichever happens last).
Kotlin-only; not exercised by the JS/Rust test suites. Verified via
ktlint parse + a release `tauri android build` and on-device smoke test
(Xiaomi). The touch-event throttle and intent-handling rewrite from the
fork are intentionally NOT backported (they dropped touchmove forwarding
and the cold-start queue).

When the Android native TTS engine is paused or stopped but not shut down,
it holds resources and drains battery. This adds a 30-minute idle timer that
automatically shuts down the TextToSpeech engine and MediaPlaybackService
after inactivity. The engine transparently re-initializes on next use.
Also adds missing androidx.lifecycle:lifecycle-process dependency to fix
ProcessLifecycleOwner build error.
Closes#3713
