Use native browser and Tauri behavior instead of custom selector, dialog, and window-state implementations. Remove obsolete bridge, relay, asset, and dependency paths to keep the supported surface small.
BREAKING CHANGE: The Noctalia relay no longer accepts --agent, and the Tauri host no longer exposes the legacy load_agent command.
Add native directory selection, persisted interface scaling, and navigation back to the latest conversation message.
Restore saved session transcripts when the bridge transcript RPC is unavailable so the desktop client remains useful during bridge compatibility gaps.
Deliver the initial local bridge, Noctalia v4/v5 adapters, desktop client, service unit, tests, and implementation documentation for persistent Pi status and control.
