add early dirty worktree check before branch operations

detect uncommitted changes before createBranchIfNeeded() attempts
to switch branches. go-git's wt.Checkout() fails with a cryptic error
when the worktree is dirty - this provides a clear error message instead.

- add IsDirty() method to pkg/git that checks for staged changes
  or modified tracked files (untracked files are intentionally ignored
  since they don't prevent checkout)
- call IsDirty() at the start of createBranchIfNeeded() after the
  "already on feature branch" early return
- add table-driven tests covering clean, staged, modified, and
  untracked scenarios
