"""ORCH-016 / TC-13..TC-15: _post_usage_comments integration tests.

End-to-end (DB + filesystem worktree, no network) verification that
AgentLauncher._post_usage_comments:
  - resolves the task by (repo, branch),
  - threads the explicit duration_s into build_status_comment,
  - posts exactly ONE status comment authored by the finishing agent,
  - for deployer: ALSO posts the per-task usage summary (deployer authorship).

The actual Plane HTTP call (plane_sync.add_comment) is patched out; we only
check the (work_item_id, body, author) tuples the launcher passes to it.
