Fix live query optimistic updates during long sync commits

[KyleAMathews]

Summary

• build on fix concurrent mutation bug #629 by also letting optimistic recomputes fire while sync commits are still running, so long-lived offline transactions remain responsive
• keep the batching tear-down and duplicate-insert tolerance from fix concurrent mutation bug #629 in the core collection bridge
• add focused regression tests for concurrent inserts, queued optimistic updates, and the offline live-query path

Testing

• pnpm vitest run packages/db/tests
