Function cursor_after_file_edit_rel_paths

src/hooks/cursor.rs:524–559

Extracts the repo-relative paths edited in a Cursor `afterFileEdit` event. Cursor sends an absolute `file_path` (plus an `edits` array). We strip the resolved `project_root` prefix and normalize to forward slashes so the hook can notify the daemon about only the changed files. Paths outside the project root are skipped.
