Wiki sync via git remote

[aniongithub]

Summary

Async sync of wiki pages to an online git store (e.g. GitHub Wiki repo) so a single wiki can span multiple machines.

Why it works

• Pages are plain .md files — git is the natural sync transport
• The SQLite index (.mind-map.db) is disposable — rebuilt by Reindex() from the filesystem
• Per-page MCP boundaries mean conflicts are rare: each mutation targets a single path

Proposed approach

• New internal/sync/ package with GitSync struct
• Track dirty pages after each MCP write via an onChange callback on the wiki engine
• Background goroutine: git pull → check conflicts → reindex → git push on an interval
• Conflict resolution: keep both versions (page.CONFLICT.md), log a warning
• CLI flags: --sync-remote <url>, --sync-interval <duration>
