 **Core flow for `link`:** `main` → `resolve_packages` → `collect_files` (recursive walk with ignore filtering) → `linker::link_package` (create symlinks or copies, record in state).
 
 Key modules in `crates/notfiles/src/`:
+
 - **linker** — Creates/removes symlinks or copies. Manages `State` (`.notfiles-state.toml`) tracking every linked file. Handles conflict detection, `--force` backups, empty-parent cleanup on unlink.
 - **config** — Parses `notfiles.toml`. Per-package overrides for method, target, ignore. Falls back to `[defaults]`.
 - **package** — Discovers packages (non-hidden subdirs) and recursively collects files via `IgnoreMatcher`.
