feat: ANR (Android) and hang detection (iOS) reporting

[bobbyg603]

Summary

Adds ANR (Android) and fatal main-thread hang detection (iOS) reporting. Both features already exist in the native libraries — this PR pulls them in and wires them up.

Android — ANR

• Updated bugsplat-android-release.aar to v1.3.0 (built from the v1.3.0 tag).
• ANR detection is automatic — AnrReporter runs inside BugSplatBridge.initBugSplat(...), no API change. Reports arrive as Android.ANR.
• Requires Android 11 (API 30+) at runtime; older OS versions are silently skipped while native crash reporting continues to work.
• Active whenever UseNativeCrashReportingForAndroid is enabled.

iOS — fatal hang detection

• Updated BugSplat.xcframework and BugSplat-macOS.dylib to bugsplat-apple v3.2.0.
• enableHangDetection is set in the iOS bridge before [BugSplat start], coupled to UseNativeCrashReportingForIos. Reports arrive as App Hang (Fatal).
• macOS hang detection is intentionally left off for now (dylib still bumped to v3.2.0 for version parity).

Sample

• New Hang / ANR button and Event_HangNative().
• _hangNativeIos() shows a confirmation alert (matching the bugsplat-apple example) explaining the force-quit-and-relaunch flow, then blocks the main thread with NSThread sleepUntilDate: — CPU-idle, unlike a spin loop.
• Flattened all crash buttons to direct On Click wiring and retired the now-unused ForcedCrashEvent relay.

Misc

• README documents ANR + hang detection.
• Package version bumped to 4.1.0.

Verification

• Android: Android.ANR report on an API 30+ device via the Hang button.
• iOS: App Hang (Fatal) report — run without the Xcode debugger attached, since hang detection is suppressed under a debugger.

Closes #121

Pull request overview

This PR wires up ANR reporting on Android and fatal main-thread hang detection on iOS by updating the bundled native libraries and exposing sample/test hooks + documentation.

Changes:

• Enabled iOS hang detection in the ObjC bridge before starting BugSplat.
• Documented ANR + hang detection and bumped the package version to 4.1.0.

• This prefab instance removes component {fileID: 5305253083977984388} (ForcedCrashEvent) but still contains override modifications targeting it (category, OnForceCrash...). Clean up these stale overrides so the instance no longer references a removed component.
