"""Tests for per-agent Plane comment authorship (feat: per-agent bot author).

Covers:
  * _headers_for: role -> bot token; None/unknown/empty token -> shared fallback.
  * add_comment: author is propagated into the POST headers; no author keeps
    backward-compatible behaviour (shared orchestrator token).

GET/PATCH calls are intentionally NOT covered here: they stay on the shared
token by design and are unchanged by this feature.
