Fix Binance trade input React rollback

[jackhai9]

Summary

• recover one exact same-node React rollback after consecutive stable frame observations
• cancel recovery when the rollback value changes, preserving fail-closed behavior for concurrent edits and repeated rejection
• add behavioral coverage for bounded recovery, replacement identities, and rejection paths
• bump the generated userscript to v2.7.135

Root cause evidence

• live CDP captured one unique visible trade form and the same quantity input identity throughout the failure
• the userscript wrote 0.07, Binance React restored the same input to an empty value within about 3 ms, and the previous one-write WeakSet then waited until the 350 ms timeout
• the failure occurs before the Binance submit button is clicked and is unrelated to network timeouts

Validation

• npm run build:binance-orderbook-trade
• npm test (364/364)
• npm run check:binance-orderbook-trade
• git diff --check
• independent read-only review: pass after narrowing recovery to the exact first rollback value
