Aligns worktree open prompting using quick picks

- Always creates a new worktree from the "main" repo
 - Automatically shows the worktree view after creation
 - Adds `worktrees.openAfterCreate` setting

Adds container, commit, branch, tag, and view node protection to the default resolver for @gate & @memoize decorators

- moves repo to the top
- adds branch and branch switching
- adds fetching
- moves account status and feedback to header
- adds PopMenu and MenuList components

VS Code made a change (or a new bug) that focuses the quickpick container rather than the input if the quick pick is disabled when it is shown
