Note

Low Risk
Dependency-only patch/minor bump with lockfile sync; risk is limited to lodash behavior changes across the codebase that already depends on it.

Overview
Bumps the pinned lodash dependency from 4.17.21 to 4.18.1 in package.json and refreshes the matching lockfile entries in package-lock.json (version, resolved URL, and integrity hash). No application source changes are included.
