feat: Add SVN commit support with GUI interface similar to Git commits

- Add SVN utility functions in src/utils/svn.ts mirroring git.ts functionality
- Add SvnCommit type and svnCommitSearchResults to ExtensionMessage
- Add searchSvnCommits message type to WebviewMessage
- Update webviewMessageHandler to handle SVN commit searches
- Update context-mentions to support SVN revision patterns (r123, @svn-changes)
- Update ChatTextArea to trigger SVN searches and display results
- Add comprehensive test suite for SVN functionality
- Implement SVN repository info extraction and working state detection

Fixes #6100
