- Redirect sys.stdout to stderr in Python sidecar so library print() calls don't corrupt the JSON-line IPC stream - Save real stdout fd for exclusive IPC use via init_ipc() - Skip non-JSON lines in Rust reader instead of failing with parse error - Set Tauri window background color to match dark theme (#0a0a23) - Add inline dark background on html/body to prevent white flash - Use Svelte tick() to ensure progress overlay renders before invoke - Improve ProgressOverlay with spinner, better styling, z-index 9999 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
