feat: add repository workspace as default project view
- Create git file utilities (list_tree, get_file_content, list_branches, commit_file) - Add file browsing API endpoints (list, content, branches, update) - Create RepoWorkspace page with sidebar + main content layout - Add FileTree component with directory navigation - Add FileViewer component for viewing file contents - Update project list to link to workspace - Add workspace CSS styles - Update router with workspace route Quality gates: ruff ✓, mypy ✓, typecheck ✓, build ✓
