Unsupported schema representation

The generator cannot represent a declaration as a valid, uniquely named plain-data schema type. This code also covers invalid schema names and conflicting definitions. Compilation fails; the last good module keeps running.

#Common causes

• A component contains reference types or a field has no supported blittable schema representation.
• An enum does not use an int or uint base with values 0, 1, 2, ... in declaration order.
• A schema name is not PascalCase letters and digits, or two different definitions use the same schema name.
• Nested value structs exceed the generator's supported nesting depth.

#Fixes

• Use supported numeric types, bool, vectors, Quaternion, Color, Entity, enums or structs composed of supported fields; remove managed references from ECS data.

• Give enums contiguous zero-based values and an int or uint underlying type.

• Give each schema type a unique PascalCase name without namespace dots, and flatten excessively nested structures.
