Review fixes for Settings ▸ Plugins:
- schema form is bound to one profile: keyed by (profile, plugin), renders
only rows loaded for that profile ($agentPluginsProfile), and its save
writes that profile or refuses; a scope switch discards the draft
- Capabilities gear carries its selected profile (&profile=), which
Settings adopts into its scope before resolving the page
- overview / missing / empty states keep the Applies-to selector
- desktop pages and automatic agent pages use disjoint identities
(kind-tagged uids; ?plugin= vs ?agent= routes)
- the folded schema form is addressed by agent key, so no plugin-chosen
sub-page id (e.g. config) is reserved
