Cherry-pick of #45129 to preview
----
Follow-up of https://github.com/zed-industries/zed/pull/44887
Trims the worktree trust mechanism to the actual `worktree`s, so now
"global", workspace-level things like `prettier`, `NodeRuntime`,
`copilot` and global MCP servers are considered as "trusted" a priori.
In the future, a separate mechanism for those will be considered and
added.
Release Notes:
- N/A
