On first launch, the app now prompts users to download the Python
sidecar (CPU or CUDA variant) from Gitea releases, matching the
voice-to-notes pattern. On subsequent launches, it auto-launches
the sidecar and connects.
New Rust module (src-tauri/src/sidecar/):
- download_sidecar: streams download with progress events, extracts zip
- check_sidecar: verifies installed sidecar binary exists
- check_sidecar_update: compares local vs latest release version
- SidecarManager: launches binary, waits for ready JSON, manages lifecycle
- Dev mode: runs `python -m backend.main_headless` directly
- start_sidecar/stop_sidecar/get_sidecar_port: Tauri commands
New Svelte component (SidecarSetup.svelte):
- First-time setup overlay with CPU/CUDA variant selection
- Download progress bar with byte counter
- Error state with retry, success state with auto-continue
Updated App.svelte state machine:
- checking -> needs_setup -> starting -> connected
- Falls back to direct connection in browser dev mode

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
