feat: Add complete async audio transcription workflow

Implemented full transcription system with local Whisper and OpenAI API
support. Includes comprehensive test suite (60 tests) and reorganized
keybindings for better discoverability.

Features:
- Async transcription (non-blocking workflow)
- Desktop notifications (started/complete/error)
- Output: audio.txt (transcript) + audio.log (process logs)
- Modeline integration showing active transcription count
- Dired integration (press T on audio files)
- Process management and tracking

Scripts:
- install-whisper.sh: Install Whisper via AUR or pip
- uninstall-whisper.sh: Clean removal with cache cleanup
- local-whisper: Offline transcription using installed Whisper
- oai-transcribe: Cloud transcription via OpenAI API

Tests (60 passing):
- Audio file detection (16 tests)
- Path generation logic (11 tests)
- Log cleanup behavior (5 tests)
- Duration formatting (9 tests)
- Active counter & modeline (11 tests)
- Integration workflows (8 tests)

Keybindings:
- Reorganized gcal to C-; g submenu (s/t/r/c)
- Added C-; t transcription submenu (t/b/k)
- Dired: T to transcribe file at point
