All supported GHES versions (3.16 through 3.20) support the
checkRunCountsByState and statusContextCountsByState fields on
StatusCheckRollupContextConnection. The slow path that iterated
individual CheckContext nodes in ChecksStatus() is dead code.
This commit:
- Removes the slow path from ChecksStatus(), keeping only the
aggregated counts-by-state path
- Removes parseCheckStatusFromCheckConclusionState (no callers remain)
- Removes CheckRunAndStatusContextCounts from PullRequestFeatures
and its introspection detection
- Consolidates the two feature detection introspection queries into
one (PullRequest + WorkflowRun fits within the platform limit of
two __type expressions)
- Removes the errgroup dependency from feature detection
- Always uses statusCheckRollupWithCountByState in pr status queries
- Updates pr view fixtures to include counts-by-state fields
