Android M1: meeting recording via foreground service

- core/recording: MeetingRecorder (AudioRecord at the device's native
  rate, WAV on disk + 60 s rolling window resampled to 16 kHz), streaming
  WavWriter, thread-safe RollingWindow, linear resampler; WavReader moved
  here from the app
- app: RecorderService (foreground, type microphone) with ongoing
  notification and StateFlow state; Record/Stop UI with timer and level
  meter; runtime permission flow; finished recordings auto-load for
  transcription
- launcher icon (mic + waveform, matching the desktop brand) and
  notification glyph
- fix real M0 bug caught by the new unit tests: WavReader parsed 16-bit
  fmt fields (audioFormat/channels/bitsPerSample) with 32-bit reads
- JVM tests: WAV round trip, native-rate header, resampler, rolling
  window — 5/5 green; assembleDebug and aapt2 APK checks pass
- validated on-device on a Fairphone 6 (Android 16): model download,
  engine load, recording and transcription all working

Add native Android app scaffold (M0): whisper.cpp engine via JNI

- android/: Gradle/Kotlin project (AGP 9.4, Compose, NDK 27.1), monorepo
  subdir as planned; whisper.cpp v1.9.3 vendored via pinned fetch script
- core/whisper: JNI wrapper (beam size, threads, language) + WhisperEngine
  Kotlin API mirroring the desktop engine contract
- app (M0 scope): in-app GGML model download from Hugging Face, engine
  load, WAV picker with resampling, on-device transcription, share sheet
- build validated: assembleDebug OK, libwhisper_jni.so + ggml packaged
