Create an integrator agent workflow that: (1) Works in the live worktree (main branch). (2) Picks up tasks in 'approved' status. (3) Cherry-picks or rebases the single commit from t-XXX onto main. (4) Verifies the build. (5) Pushes to main. (6) Deletes the t-XXX branch (cleanup). (7) Marks task 'done'.
Rewrote Omni/Ide/Workflows/integrator.md for approved->done integration: cherry-pick single task commit from t-XXX onto live, verify, mark done, and safe branch cleanup.
