formatCheckRun now sets a stable updateKey (check_run:{repo}:{id}) so queued → in_progress → completed phases update the original message via KV msg:* tracking instead of posting new ones. Adds tests and syncs README/docs.
Unify all branch, commit hash and tag references across formatters to the push commit style (inline code + link). Adds commitLink/branchLink/tagLink helpers in formatters/helpers.ts, links branches to /tree/, tags to /releases/tag/, and PR head branches to the fork repo. Drops the backticks from the en/zh locale templates around {ref}/{sha} since the formatters now inject pre-linked values.
Add clickable commit links in check_suite formatter output with fallback
URL when html_url is unavailable. Remove check_run from checks template
since formatter only handles check_suite events.
