chore: re-trigger Gitea Actions workflows (core-devops agent)

The queue was retrying the same PR forever when merge returned HTTP 405
("User not allowed to merge PR"). ApiError was caught by main() and returned
0, so the next tick tried the same PR again — infinite loop.

Changes:
- Add MergePermissionError(ApiError) for permanent merge failures
- merge_pull() catches ApiError and re-raises MergePermissionError for
  HTTP 403/404/405
- process_once() catches MergePermissionError, posts a comment on the PR
  explaining the permission issue, and returns 0

The PR stays in the merge-queue label so future ticks can retry after
the permission issue is resolved.
