v1.0.45

Files workspace connection fix\n\n- Restores Connect for explicit storage profiles, including local Windows storage and remote Owner Machine/SFTP connections.\n- Automatically selects the active Agent node once without clearing later profile choices.\n- Tracks complete provider targets so disconnect, reconnect, refresh, and profile switching stay consistent.\n- Deduplicates concurrent Connect requests and shows sanitized, actionable connection failures.\n- Adds authenticated Agent file mutations for editing, create, copy, rename, delete, and upload within configured file roots.\n- Blocks configured-root deletion and rate-limits Agent file mutations.\n- Updates the release workflow to publish both Windows installer and portable builds.\n\n## Validation\n\n- Dedicated Files pipeline smoke: local and authenticated Agent connect/reconnect, listing, browsing, open, edit, create, copy, rename, delete, and root protection.\n- Live Agent listing and edit/read/delete verification on the configured Debian endpoint.\n- Project validation, Agent syntax checks, Marketplace smoke, node switching smoke, and git diff checks.\n- Windows NSIS installer and portable x64 builds completed and were signed by the configured build workflow.
