refactor(scripts/wiki): rewrite markdown links when syncing impl docs to wiki

- Convert intra-repo README links to VitePress routes for SPA navigation
- Rewrite source file references (e.g., config.go:29) to GitHub blob links
- Makefile now passes REPO_URL to update-wiki for link rewriting
- Correct agent README.md file links from full to relative paths
- skip introduction.md when syncing
