Fix docs-only CI check to allow running workflows

The safety check was blocking docs-only commits whenever the previous
master commit had ANY running workflows, even if they hadn't failed yet.
This created a bottleneck when workflows were slow (e.g., integration tests).

Changes:
- Allow docs-only skips when previous workflows are running (not failed yet)
- Only block if completed workflows have actually failed
- Add informative logging about running vs failed workflows

Rationale:
- Running workflows haven't failed yet → no known issue to block on
- They will complete and validate the previous commit independently
- Eliminates bottleneck from slow-running workflows
- Still maintains safety by blocking on actual failures

Fixes the circular dependency issue where docs-only commits couldn't
merge because previous commit's workflows were still in progress.
