Propagate collection retrieval failures instead of treating them as empty results. If get_commits() or another collection fetch fails or returns None, stop processing or preserve an explicit incomplete state. Otherwise PR commits can be emitted as direct commits, and failed issue or commit retrieval can silently produce incomplete or overly broad release notes. Apply this consistently at the affected collection-retrieval sites.

Materialize release-mode issue pages inside the safe-call wrapper. PyGithub performs pagination during iteration. In release mode, list(issues_since) and list(open_issues) run outside the wrapper, so pagination errors escape. Use self._safe_call(lambda: list(...))() for both calls.
