vault-presync

Pre-sync helper that handles the full sync pipeline for the ~/wiki vault: lint gate, untracked-file collision removal, conflict detection, and rebase-based merge.

When to use

• Before git push from the ~/wiki vault (after editing sessions)
• When git pull fails with "The following untracked working tree files would be overwritten by merge"
• When git merge --ff-only fails due to divergent histories (local + remote both have commits)
• After a Claude Code session that modified vault files
• Periodically to keep the local vault in sync with sg01 30-minute snapshots
