fix(push): gracefully handle errors identifying potential PR merges

Errors from get_merged_status_events no longer abort the push; the
call site now uses if let Ok(...) so failures are silently skipped.
Also replace an .unwrap() in create_merge_events with a safe
.map().unwrap_or_default() to avoid any panic in that path.
