refactor(formula): Move cleanup-worktrees earlier in sync workflow (gt-gqiwm)

Reordered mol-sync-workspace.formula.toml so cleanup-worktrees runs after
handle-dirty-state instead of after run-tests. This is more logical:
worktree cleanup is housekeeping that should happen during workspace prep,
not after verification steps.

New execution order:
1. assess-state
2. handle-dirty-state
3. cleanup-worktrees  ← moved here
4. sync-git
5. sync-beads → run-doctor → verify-build → run-tests
6. generate-report → signal-ready
