Runs the captureReplay buffer-priming and assertReplay check on Android in addition to iOS. Android has never asserted replays in CI (see #4277, "android doesn't seem to capture replays in CI"); this re-evaluates that now that deterministic buffer priming lands the assertion reliably on iOS. Relax the codec assertion from an exact `ftypmp42` major brand to a valid MP4 container check (the "ftyp" box), since iOS (AVAssetWriter) and Android (MediaMuxer) can emit different major brands for the same valid MP4. The Android E2E result on this PR is the deliverable: it empirically shows whether Android now captures a replay in CI. If red, keep the assertion iOS-only.

📜 Description
Extends the
captureReplaye2e test to run the buffer-priming step and theassertReplaycheck on Android, not just iOS — the second half of #6082 ("evaluate adding an equivalent Android check").maestro/captureReplay.yml— remove theplatform: iOSgates so priming +assertReplayrun on both platforms. TheReplay Pingprimer (testID='replayPing') is already platform-agnostic (RNtestIDmaps to a resource-id Maestro can tap on Android).maestro/utils/assertReplay.yml— relax the codec assertion from the exactftypmp42major brand to a valid-MP4-container check (theftypbox at byte offset 4). iOS (AVAssetWriter) emitsmp42; Android (MediaMuxer) can emit a different brand such asisomfor the same valid MP4, so the exact-brand check would false-fail on Android. iOS still passes (ftypmp42starts withftyp).💡 Motivation and Context
Second half of #6082
