## Message

```
worktrees: reject refs/heads and @{ branch names on create (#146)

worktree.create only ran git check-ref-format --branch, which still
accepts refs/heads/foo and @{-1}. The former creates nested
refs/heads/refs/heads/...; the latter expands to another branch.
Reuse validate_branch_name (same rules as task.start) so prefs/theme
stays valid while those traps are refused.
