The package-lock.json was inadvertently deleted in commit 3e5cc26 (PR #189), causing CI workflows (static.yml, merge.yml) to fail since they depend on `npm ci` which requires this file. This restores the file from the commit immediately prior (b4838e8). Made-with: Cursor Co-authored-by: Aravind . <aravind@backbase.com>
