revert: undo workflow if-condition gating for pull_request_comment

Forgejo's pull_request_comment payload does not populate
github.event.comment.body or github.event.review.body in a way
the workflow contains() expression can read, causing legitimate
@claude reviews to be skipped (run 12084).

Revert to unconditional pass at the workflow level. The @claude
check is handled properly in trigger.ts which inspects the actual
payload fields with fallback logic.
