Gitignore backups/, add memory git sync, update daily service

- .gitignore: Add backups/ to stop noisy session backup rotation diffs
- Remove tracked backup files from index
- skills/cognitive-memory/mcp_server.py: Auto-push to Gitea on memory_store and memory_relate
- skills/cognitive-memory/scripts/memory-git-sync.sh: New git commit+push script
- skills/cognitive-memory/systemd/cognitive-memory-daily.service: Add git sync as fallback
