Test plan

1. Run pnpm test - all existing tests pass

3. Run shopify app deploy - web build does NOT run
4. Verify admin_link extensions still work correctly

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
