Merge origin/master into worktree/web-plugin-config, adapting to ctx.remote.$on

#2201 landed three moves this branch sits on top of. `bindSettingsScope` became
`ctx.settingsScope.bind` on the Settings surface, so the section injects that
service and the Remote face instead of importing a free function; the
`SettingsScope` types moved into the runtime contract module, which is where
this branch's `base`, `user`, and `unset` now live; and the client
`credentials/changed` event became the forwarded owner event
`credentials/updated`, which the web-search card subscribes to through
`ctx.remote.$on`.

The generated module graph crossed mermaid's 1000-edge render guard with this
branch's 14 new edges. The guard doubles again, exactly as it did at 500 — the
graph counts real package edges, and trimming them to fit a renderer default
would make the document lie about the dependency set.
