context_server: Only look for context server project settings in visible worktrees (#27633)
Marshall Bowers
and

created
This PR fixes an issue where we were looking for context server project
settings in _all_ worktrees, not just visible ones.
This meant that if you had a single file worktree open (e.g.,
`settings.json`) this could impact whether context servers defined in
project settings would load.
Release Notes:
- Fixed an issue where context servers defined in project settings would
not be respected in some scenarios.
