v1.9.30

Changed: Performance: heavy file I/O commands (get_project_versions, thumbnail extraction, update_project) moved to a dedicated thread pool — the UI no longer blocks while they run

Changed: Performance: version list requests are deduplicated — rapid project switching fires one IPC call instead of several in parallel

Changed: Performance: file tree and folder size now cached per-project — switching back to a recent project is instant

Changed: Performance: thumbnail hooks skip the mtime check on remount when the image is already in memory; only re-check after the window regains focus

Fixed: Versions: stale load results from a previous project are now discarded, preventing phantom version lists on fast switching
