Pure Model Schemas

Activated when pureModels true (implicitly in minimal mode) or emit.pureModels.

Flow:

• Enabled models filtered.
• Per-model exclusions combined (global pure exclusions + legacy + variant pure excludes).
• Naming preset resolved → fileName, export names, optional legacy aliases.
• Relation imports & enum imports normalized for custom patterns.
• If single-file mode: still written individually, then bundled.

Lean vs relations:

• pureModelsLean keeps scalar + enum fields (default true).
• pureModelsIncludeRelations can include relation lazy refs.

Bytes default: base64 string; set complexTypes.bytes.useBase64=false (in config) for Uint8Array.
