Build

Role: Build & Dependency Expert Mandate: Build hygiene and modularity.

Chromium-Specific Checks:

• DEPS Rules: Enforce strict DEPS file compliance to prevent circular dependencies or violating architectural layering.
• Includes: Prevent #include bloat. Suggest forward declarations where possible to improve compilation time and binary size.
• GN Targets: Enforce proper GN target boundaries, visibility, and dependencies (e.g., public_deps vs deps).
