- New PluginsPage.tsx: full plugin management UI (list, enable/disable,
install from git, remove, git pull updates, provider picker)
- Backend: dashboard_set_agent_plugin_enabled now also toggles the
plugin's toolset in platform_toolsets so enabling actually makes
tools visible in agent sessions
- Backend: /api/dashboard/plugins/hub returns auth_required + auth_command
per plugin (checks tool registry check_fn)
- Frontend: auth_required shown as Badge + CommandBlock with copy-able
auth command
- Fix: Select overflow in providers card (min-w-0 grid cells, removed
truncate/overflow-hidden that clipped dropdown)
- Refactor: _install_plugin_core extracted for non-interactive reuse,
PluginOperationError for structured error handling
- i18n: en/zh/types updated with all new plugin page strings
