9ed0639005 fix(fugitive): handle renamed files correctly 
Parse both old and new filenames from rename lines (R old -> new).
When diffing staged renames, use old filename as base to correctly
show content changes rather than treating the file as entirely new.

Also adds comprehensive tests for filename edge cases:
- Double extensions, hyphens, underscores, dotfiles
- Deep nested paths, complex renames
- Documents known limitation with filenames containing ' -> '

6072dd0156 feat(fugitive): add section header and untracked file support 
Section headers (Staged/Unstaged) now show all diffs in that section,
matching fugitive's behavior. Untracked files show as all-added diffs.
Deleted files show as all-removed diffs.

Also handles edge cases:
- Empty new/old content for deleted/new files
- Section header detection returns is_header flag
