chore(env): update Flutter and SDK constraints for compatibility

- Downgraded Flutter version in .fvmrc from 3.29.3 to 3.27.0 for compatibility with current dependencies
- Raised Dart SDK constraint in benchmark_di/pubspec.yaml from >=3.0.0 <4.0.0 to >=3.2.0 <4.0.0 to align with required package minimums

This change ensures environment compatibility for dependency resolution and build tools. No functional code changes.
