fix: normalize native engine import paths to remove . and .. segments

The Rust resolve_import function produced paths like src/./db.js
because Path::join preserves . segments from relative imports.
This caused import edges to be lost for native engine users.

Fix by normalizing the resolved PathBuf immediately after join using
components().collect(), and upgrading normalize_path to also clean
. / .. segments. Remove the temporary path.normalize() JS workaround
since the Rust side now returns clean paths directly.
