Add 10 end-to-end tests that simulate asymmetric network latency between two collaborating users (800ms delay on User B wp-sync polling via Playwright route interception). Tests cover: - Traffic capture proving latency injection is measurable - Concurrent edits resolving to identical CRDT state - Interleaved block inserts with no data loss - CRDT document persistence after save + reload - Stress: 10 rounds of rapid alternating inserts (20 blocks) - Stress: simultaneous burst of 8 blocks per user (16 total) - Stress: mixed block types (headings, lists, quotes) + attribute changes - Stress: block deletion + insertion convergence - Stress: concurrent edits then save/reload data integrity - Request volume: high-latency user does not flood the server

Summary
Adds 10 end-to-end Playwright tests that simulate asymmetric network latency between two collaborating users editing the same post with Real-time Collaboration enabled.
User A has a normal connection. User B has 800ms of artificial delay injected on all
wp-syncpolling requests via Playwrightpage.route()+route.fetch()+setTimeout. This creates a realistic scenario where one user CRDT updates arrive late and must be merged with the other user newer state.Tests
Local results
All 10 tests pass consistently (20/20 across --repeat-each=2, ~11s per test).
