fix: keep review and release events in github-data.yaml and LLM context

Review events show which PRs were approved/rejected (not available
from PR data alone). Release events provide tag/name info not in
commits or PRs. Other event types (PushEvent, CreateEvent, etc.)
remain excluded as their payloads are empty.
