Migrate action query from text to protobuf parsing

[sean7218]

Summary

This PR modernizes the action query functionality by migrating from plain text parsing to protocol buffer (protobuf) parsing for Bazel action query results. This change improves reliability, type safety, and maintainability of compiler argument extraction.

📝 Key Changes

• Replaced text-based parsing with protobuf parsing in BazelTargetAquerier
• Added --output proto flag to all aquery commands to generate protobuf output
• Simplified argument processing logic in CompilerArgumentsProcessor by leveraging structured data
• Updated test resources with binary protobuf files (aquery.pb and aquery_objc.pb)
• Enhanced command runner with dedicated bazelActionQuery method for protobuf data handling

✨ Benefits

1. Improved Reliability: Eliminates fragile text parsing that could break with format changes
2. Type Safety: Leverages Swift's type system with protobuf-generated structs
3. Better Performance: More efficient binary parsing vs. text processing
4. Enhanced Maintainability: Cleaner, more readable code with structured data access
5. Future-Proof: Protobuf format is stable and versioned by Bazel

🧪 Testing

• Updated all test expectations to use protobuf output format
• Added binary test resources for both Swift and Objective-C action queries
• Maintained existing test coverage while improving test data accuracy

Works perfectly. Thanks Sean!
