feat(ios): W3 UI layer + integration CI + ntfy docs

T-iOS-11: TerminalScreen/KeyBar/TerminalViewModel + KeyByteMap (byte-for-byte keybar.ts, arrows excluded from UIKeyCommand to preserve DECCKM)

T-iOS-13: SessionListScreen/VM — Tunables-paced polling with leak-free teardown, optimistic kill+rollback, pending via overlay (LiveSessionInfo has no pending field)
T-iOS-14: GateBanner/PlanGateSheet/AwayDigestView/GateViewModel — three-way mapping from SessionCore Affordance single source, tap-epoch guard, per-epoch haptics
T-iOS-16: IntegrationTests vs real Node server (10 tests: origin guards, mirror, kill-close vs exit-frame differential, 16MiB+ESC/C0 replay) + ios.yml own-sources coverage gate (red-once demoed)
T-iOS-17: ios/README.md ntfy chapter (read-only verification, file:line cites)
