- Add resourceVersion handling for Watch requests by filtering ADDED events based on the resourceVersion provided by the client - Forward bookmark events from underlying HelmRelease watchers to clients for proper resourceVersion synchronization - Extract MaxResourceVersion helper using meta.EachListItem for cleaner code - This ensures clients don't receive duplicate objects they already have from List+Watch patterns Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: Andrei Kvapil <kvapss@gmail.com>
