fegger 8e079467fa 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

fegger e5ec95a5fb Add app icon (mic + waveform) and fix desktop categories
- share/icons/hicolor/: SVG source + PNG fallbacks (48-256 px); the
  desktop entry now uses Icon=meetrec instead of a stock theme icon
- install.sh installs the icon into the hicolor tree, refreshes the
  GTK icon cache, and cleans up on uninstall
- Categories fixed to AudioVideo;Audio per the menu spec (bare Audio
  is a subcategory requiring its main category); desktop-file-validate
  is clean now

fegger e14a6bfe9f Record at the input device's native sample rate
- Recorder queries default_samplerate and streams/WAVs at that rate
  instead of forcing 16 kHz (helps devices that don't support it
  natively and keeps recordings at full fidelity)
- new resample_16k() linear resampler: the live rolling window is
  converted to Whisper's 16 kHz before being handed to the engines
- snapshot() now returns (16 kHz audio, absolute start time in s)
- final pass unchanged: faster-whisper (PyAV) and whisper.cpp
  (miniaudio) resample native-rate WAVs themselves
- GUI status shows the active rate; README updated

Validated with real 44.1 kHz and 48 kHz inputs: WAV headers match the
device rate, live-window resampling is length- and spectrum-correct.

fegger 404f3db200 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

fegger 66408e291d Add whisper.cpp engine with Vulkan GPU support (AMD/Intel/NVIDIA)
- meetrec.py: engine layer with a common transcribe() contract;
  WhisperCppEngine shells out to whisper-cli, GGML + Silero VAD models
  auto-download to ~/.cache/meetrec; faster-whisper import now lazy;
  new --engine CLI option
- meetrec_gui.py: Engine dropdown; Device/Compute greyed out for
  whisper-cpp; model reload keyed on (engine, model, device, compute)
- install.sh: --whisper-cpp builds whisper.cpp with -DWHISPER_VULKAN=ON,
  installs whisper-cli into the prefix and wires WHISPER_CPP_BIN via a
  generated whisper-cpp.env; build failures degrade to a warning
- launchers source whisper-cpp.env; README documents engines
- Recorder.stop() is now idempotent (GUI close path called it twice)

fegger 18ce1c134c Initial commit: MeetRec — record & transcribe meetings with Whisper
- meetrec.py: CLI recorder with live rolling transcript (faster-whisper)
- meetrec_gui.py: PySide6 GUI reusing the CLI's recording/transcription
  logic, with model/device/compute selection and live transcript
- install.sh: local install into ~/.local (venv, deps, launchers,
  desktop entry), with --model/--no-model/--uninstall
- bin/meetrec, bin/meetrec-cli: launchers
- share/applications/meetrec.desktop: XDG desktop entry
- README.md, requirements.txt, .gitignore
