DEVX-118: refactor: rewrite sync_wiki.py to use git-based approach

Replace the unreliable Gitea wiki API with direct Git operations:
- Clone {repo}.wiki.git, copy docs with link transformation, push
- Faster: single git push vs N API calls
- More reliable: no API timeouts or rate limits
- Atomic: all pages sync in one commit
- Auto-pruning: stale wiki pages removed automatically
- Link transformation: [text](file.md) → [text](file) for wiki format
- 36 new tests covering transform_links, clone, sync_files, commit, verify

-  - Create: POST /repos/{owner}/{repo}/wiki/new  {title, content_base64, message}

+The wiki Git URL is ``{clone_url}.wiki.git`` (Gitea convention).
