v0.1.0

Use unique ids to coexist with official web-app row

The web-app bundle already ships a loader row with id ui-session-manage
(the shipped client plugin), and a duplicate entry id fails the boot. The
standalone package now uses its own id for the loader row, the settings
slot, and the locale namespace, so it installs cleanly on any deployment
including current official ones. Document the required -w flag (profile
pnpm-workspace.yaml makes bare add fail) and the coexist behavior.
