The shared agent.yml is a reusable (workflow_call) workflow, so on Gitea
github.event_name evaluates to 'workflow_call' — not the original 'issues'/
'issue_comment'. route.sh branched on EVENT == "issues", so issue-opened runs
scanned the empty comment body and skipped the @pm fallback, exiting 1 with
"no known agent mentioned" (runs #393/#394). Comment runs were unaffected
because the @mention lives in $BODY.
Discriminate on the comment id (CID) instead, which IS reliably forwarded in
the event payload: empty => issue-opened (scan issue body, default @pm), set
=> comment (scan comment body). Also add .gitignore for .env.
