Subject: [PATCH 1/3] feat(github): enrich check resource events with trusted
 data

Give check suite events action handles (SHA, suite id/url, failing checks)
so Junior can act without rediscovering CI state on every turn.

Subject: [PATCH 3/3] fix(github): keep check names out of trusted event data

Review feedback: check-run names are workflow-controlled, so put them in
untrustedText. Load failing runs by suite id, and build the suite browser
url ourselves because GitHub does not send html_url on check suites.
