fix: stabilize iOS runner gestures

[thymikee]

Summary

Fix three iOS runner issues found during replay-suite validation: avoid stale XCTest window-index queries during AX snapshot fallback viewport discovery, route iOS phone/tablet drag gestures through synthesized drag so durationMs controls swipe, gesture pan, gesture fling, and repeated swipe sequences, and keep macOS/tvOS on the existing coordinate/focus paths.

This stays inside the ADR 0004/0005 runner seam: Swift runner changes remain local to viewport discovery and sequence execution, while TS platform overrides only request the synthesized path for iOS touch targets. Touched files: 6 in the latest follow-up, 8 across the PR.

Validation

Static/build checks on this clean branch: pnpm check:quick, pnpm build:xcuitest, pnpm build, focused Vitest for src/platforms/ios/__tests__/index.test.ts and src/core/__tests__/dispatch-interactions.test.ts, full oxfmt coverage using the local formatter binary, and local Fallow audit via ./node_modules/.bin/fallow audit --base origin/main. Direct pnpm check:fallow --base origin/main was blocked by pnpm version-switch network verification before project code ran; the local Fallow binary passed the audit gate.

Live simulator evidence used iOS simulator C25DBB5B-9254-4293-A8D5-2785C78DE03A with React Navigation org.reactnavigation.playground. material-top-tabs.yml passed in 20.1s / 20.2s wall with three duration: 300 swipes; runner drag windows were about 0.91s / 1.29s / 0.97s and the old XCTest velocity of 500 coordinate-drag log was absent.

Fresh direct duration checks in session ios-duration-gestures also passed: gesture pan 350 500 -300 0 300 completed in 0.89s, gesture fling right 200 500 180 50 in 1.12s, and swipe 350 500 50 500 300 --count 2 --pause-ms 30 --pattern ping-pong in 1.42s. Runner logs showed the expected drag/sequence commands completing with no gestureFallback, no xctest-coordinate-drag, and no velocity of 500 marker. Manual sessions were closed, custom daemon state dirs were cleaned, and process checks found no remaining validation runner/xcodebuild processes.

[thymikee]

Addressed the review parity gap: repeated iOS swipe/sequence drag now uses synthesizedSwipeFallbackHoldDuration(durationMs:) when synthesized drag is unavailable, matching the single-shot drag command. Also corrected the sequence coordinate-drag comment to describe only the non-synthesized branch. Validation: pnpm build:xcuitest passed for iOS and macOS.
