[build-tools] replace record-sim with serve-sim recording

[gwdp]

Why

The session runner used record-sim to capture the framebuffer separately from serve-sim. The new serve-sim stack owns one native capture and a dedicated hardware recording encoder, so build-tools can use its recording client and keep the existing upload manifest.

Depends on expo/expo-device-hub#164–#167 being released in order before this consumer.

How

Start serve-sim record-video from the selected serve-sim package after its token-bearing preview is ready, wait for its start marker, and stop with SIGINT. Recording begins with that preview; footage before serve-sim startup is outside this recording. If serve-sim stops first, it finalizes the file during shutdown while the client waits for the manifest. Give the serve-sim process group up to 90 seconds after SIGTERM before SIGKILL, even when its package-manager wrapper exits early. Remove record-sim packaging; the upload step is unchanged.

Test Plan

• corepack yarn jest-unit --runInBand src/steps/utils/__tests__/IosSimulatorRecordingUtils.test.ts src/steps/utils/__tests__/remoteDeviceRunSession.test.ts: 75 passed, including a wrapper-exit recording regression.
• corepack yarn typecheck in build-tools, root corepack yarn lint, and root corepack yarn fmt:check: passed.
• The matching local serve-sim binary produced a decodable MP4 and the existing manifest in pinned Tart iPhone 17, Xcode 26.4, with two concurrent H.264 viewers. A separate SIGTERM run confirmed finalization and client manifest wait.
• Hosted EAS worker execution remains unverified. Release serve-sim before this consumer.

[gwdp]

Codex contribution: switched the iOS Simulator recording consumer to serve-sim record-video, preserved the upload manifest, and added retry and shutdown coverage. After rebasing onto current main, I fixed wrapper-exit tracking so a live recorder remains owned by its process group; the focused 75 tests, typecheck, lint, and formatting checks pass.
