Replace Process.runSync('which', ['-a', 'dart']) in Health with dartExecutable from package:cli_util (^0.6.0).

Using package:cli_util provides cross-platform Dart SDK and dart executable resolution (supporting Platform.resolvedExecutable, DART_ROOT/DART_SDK, PATH with Flutter wrapper awareness, and FLUTTER_ROOT) both in JIT and when firehose executables are compiled to standalone AOT binaries (dart install / dart run firehose@).

Part of dart-lang/sdk#63210

Code Review

This pull request replaces the manual shell command which -a dart with the cli_util package to resolve the Dart executable path in the Health class, updating dependencies, the changelog, and adding a unit test. The review feedback correctly points out that cli_util.dartExecutable is non-nullable, meaning the null-coalescing operator (??) is redundant and should be removed to avoid static analysis warnings.

Comment on lines +90 to +91
dartExecutable = cli_util.dartExecutable ??
(throw StateError('Could not locate a Dart executable.'));

cli_util.dartExecutable is a non-nullable String (it throws a StateError internally if the SDK cannot be found). Using the null-coalescing operator ?? here is unnecessary and will trigger a static analysis warning (unnecessary_null_aware_operator). You can assign it directly.

Suggested change
dartExecutable = cli_util.dartExecutable ??
(throw StateError('Could not locate a Dart executable.'));
dartExecutable = cli_util.dartExecutable;

dartExecutable = dartExecutables
.sortedBy((path) => path.contains('flutter').toString())
.first;
dartExecutable = cli_util.dartExecutable ??

Probably this should be covered by a test but isn't: The original code was meant to get the right Dart, not only a Dart, when there is both a Flutter and Dart installed. I think there were some issues surrounding this at some point... But I can't really remember so I would say we merge and see if there is breakage downstream :)
