• Add a unit test to verify that the REST client sets the user-agent header to javascript-client/<PACKAGE_VERSION>, ensuring future changes don't break this behavior.

        const headers = new Headers([['user-agent', 'javascript-client/' + String(PACKAGE_VERSION)]]);

packages/js-client-grpc/src/api-client.ts:55

• Add a test for the gRPC interceptor to confirm that the user-agent header is correctly set to javascript-client/<PACKAGE_VERSION> on every request.

            req.header.set('user-agent', 'javascript-client/' + String(PACKAGE_VERSION));

[nitpick] Consider extracting the 'javascript-client/' + String(PACKAGE_VERSION) value into a shared constant to avoid duplication between REST and gRPC clients.

Suggested change

	const headers = new Headers([['user-agent', 'javascript-client/' + String(PACKAGE_VERSION)]]);
	const headers = new Headers([['user-agent', USER_AGENT]]);

[Copilot]

[nitpick] Consider moving the user-agent string construction into a shared utility or constant to keep the REST and gRPC implementations consistent and DRY.

Suggested change

	req.header.set('user-agent', 'javascript-client/' + String(PACKAGE_VERSION));
	req.header.set('user-agent', getUserAgent());
