fix: harden iOS replay runner prewarm

[thymikee]

Summary

• Health-check iOS runner prewarm through the existing prepare/uptime path so stale cached runners are recovered before replay commands.
• Stop stale Apple runner sessions during iOS relaunch across CLI process boundaries: first shut down any in-memory session, then terminate device-scoped xcodebuild test-without-building runner processes left by standalone prepare.
• Clean stale device-scoped xcodebuild runner processes before launching a new local runner session, so CI remains reliable even when prepare ios-runner was skipped.
• Start normal iOS runner prewarm after app open, while preserving the Maestro before-open path.
• Add runner command lifecycle log lines and upload iOS replay attempt artifacts under test/artifacts paths.
• Touched files: 9; scope stayed within iOS replay runner reliability, session open ordering, workflow artifacts, and diagnostics.

Validation

• pnpm exec vitest run src/platforms/ios/__tests__/runner-session.test.ts src/daemon/handlers/__tests__/session.test.ts src/platforms/ios/__tests__/runner-command-retry.test.ts
• pnpm check:quick
• pnpm build
• pnpm build:xcuitest
• node --experimental-strip-types src/bin.ts prepare ios-runner --platform ios --timeout 300000 --json
• node --experimental-strip-types src/bin.ts test test/integration/replays/ios/simulator/01-settings.ad --retries 2 --artifacts-dir test/artifacts/replays-ios-simulator-smoke-local-stale-kill --report-junit test/artifacts/replays-ios-simulator-smoke-local-stale-kill.junit.xml passed first attempt in 13.9s; runner log showed the stale prepared runner ended with BUILD INTERRUPTED, not XCTest TEST EXECUTE FAILED.
• No-prework validation: after pnpm clean:daemon, ran node --experimental-strip-types src/bin.ts test test/integration/replays/ios/simulator/01-settings.ad --retries 2 --artifacts-dir test/artifacts/replays-ios-simulator-smoke-local-no-prework --report-junit test/artifacts/replays-ios-simulator-smoke-local-no-prework.junit.xml; passed first attempt in 16.6s, with open doing runner prewarm and subsequent runner-backed actions completing quickly.
• pnpm check:unit was rerun outside the sandbox and failed in unrelated Android .aab tests; rerunning that file directly passed: pnpm exec vitest run src/platforms/android/__tests__/index.test.ts
