fix(ui): external adapter UI parser can now override builtin parsers

Builtin adapter types (hermes_local, openclaw_gateway, etc.) could not
be overridden by external adapters on the UI side. The registry always
returned the built-in parser, ignoring the external ui-parser.js shipped
by packages like hermes-paperclip-adapter.

Changes:
- registry.ts: full override lifecycle with generation guard for stale loads
- disabled-overrides-store.ts: client-side override pause state with
  useSyncExternalStore reactivity (persisted to localStorage)
- use-disabled-adapters.ts: subscribe to override store changes
- AdapterManager.tsx: separate controls for override pause (client-side)
  vs menu visibility (server-side), virtual builtin rows with badges
- adapters.ts: allow reload/reinstall of builtin types when overridden
