feat(path): rename-aware ambiguity resolution for suffix probe

When a bare filename like 'operators.ts' matches multiple full paths,
check if they are the same file connected by renames (via BFS on
mr_file_changes). If so, auto-resolve to the newest path instead of
erroring. Also wires path resolution into file-history and trace
commands so bare filenames work everywhere.
