TwinTrade 0.42.0 — Synchronized mark/index order frames

Live opens and closes now require fresh mark and index prices from synchronized frames before review and again immediately before contract simulation or submission. If the feed splits while wallet approval is confirming, TwinTrade stops before sending the trading transaction.

Validation covers skew in both timestamp directions and a split during approval. JavaScript and native regression suites, release integrity, APK signature/alignment, browser controls/rotation and Android lifecycle checks gate publication. No funded transaction was sent.
