Scaffold the cross-platform rewrite from PySide6/Qt to Tauri + Svelte,
following the same architecture as voice-to-notes. The Python backend
runs headless as a sidecar, with a FastAPI control API that the Svelte
frontend connects to via REST and WebSocket.
New files:
- backend/app_controller.py: Headless orchestration (extracted from MainWindow)
- backend/api_server.py: FastAPI control endpoints + /ws/control WebSocket
- backend/main_headless.py: Headless entry point for sidecar mode
- src-tauri/: Tauri v2 Rust shell with sidecar and dialog plugins
- src/: Svelte 5 frontend (App, Settings, Controls, TranscriptionDisplay)
- src/lib/stores/: Reactive stores for backend connection, config, transcriptions

New files:
- client/deepgram_transcription.py — DeepgramTranscriptionEngine with
managed mode (proxy) and BYOK mode (direct Deepgram). Sends raw binary
PCM audio over WebSocket, handles both proxy and Deepgram response formats.
Modified files:
- config/default_config.yaml — Replace remote_processing with new remote
section (mode, server_url, auth_token, byok_api_key, deepgram_model, language)
- client/config.py — Add migration from old remote_processing config
- gui/settings_dialog_qt.py — Replace Remote Processing group with
Transcription Mode section (Local/Managed/BYOK radio buttons, login/register
dialogs, balance display, model selector)
- gui/main_window_qt.py — Select engine based on remote.mode config,
add error and credits_low handlers
