Bugfix: UsePlayerUpdateJobs 2 - maintain partial ordering of snapshots when sending to player using tasks
- This fixes rare parenting desync that can manifest as a weapon attachment world model not hiding (or something much worse)
Need to optimize it by merging tasks, as this can create too many tasks for the server to process
Tests: flew around on Craggy with fast noclip - attachments didn't "duplicate". Shot animals, switched active items. Tested occlusion with 2p and geared guns
