Add sidecar download, setup screen, and auto-launch
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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
