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

In case of multiple cursors (selections) in the same line, an
annotation was created per selection, resulting in an odd experience.
Filter out duplicated lines by the line number.
