Retire ACP/Hermes/OpenCode surfaces and rename hermes_tools to
mnote_agent_tools so Page AI stays on Pi Lab only. Add Chrome vault
extension + extension token route, pre-release purge design, and soft-retire
legacy smokes for the small-group production cut.
- scope local-folder PageTree revision and document sidebar rendering to fileTreeScope
- preserve projected table/image attrs for local Markdown aggregate fallback
- avoid FileTree restore forced layouts on cold design open
- add API ChatOnly provider runtime and local OCR task handling regressions
