Strict Header Self-Containment

Every header file (.h) in Filament must be fully self-contained and compile independently.

• Rule: Never assume a header's type dependencies (like FrameGraphHandle) are pre-declared by preceding includes in a .cpp file.
• Action: Always explicitly #include the declaring header (e.g., fg/FrameGraphId.h) inside the header itself.
