v0.4.1

Fix

• Fixed first-run and post-cleanup sidebar routing writes. The plugin now creates the sidebar state directory before acquiring its cross-process file lock, so session routing state is persisted even when the directory does not yet exist.

Documentation

• Updated the architecture reference for Responses Lite, per-session sidebar routing, dynamic quota windows, and model-cost restoration.
