Code Review
This pull request refactors the iOS device log reading mechanism to introduce a generic LogInterceptor. This new system is then used to intercept and display a guided warning for UIScene related device logs. The refactoring also encapsulates the existing JIT crash log interception into a LogInterceptor. The changes are well-structured and improve the extensibility of log processing. I've found one area for improvement in the new log interception logic.

The current implementation of _interceptLog stops processing interceptors after the first match. If the first matching interceptor has excludeFromStream: false, it returns false immediately, and any other interceptors that might also match (and potentially want to exclude the log) are never checked. This could lead to unexpected behavior if multiple interceptors could match the same log line.
To ensure all matching interceptors are processed, you could iterate through all of them, execute their actions, and then decide whether to exclude the log based on whether any of them requested exclusion.
bool _interceptLog(String message) {
bool shouldExclude = false;
for (final LogInterceptor interceptor in _logInterceptors) {
if (message.contains(interceptor.pattern)) {
interceptor.action();
if (interceptor.excludeFromStream) {
shouldExclude = true;
}
}
}
return shouldExclude;
}
