/**
 * Go code emitter — Declaration IR → Go source code.
 *
 * Replaces `file.go.njk` Nunjucks template with a typed TypeScript function
 * that walks the TypeDecl tree and produces a complete Go source file.
 *
 * Each file contains one type hierarchy (parent + children).
 * Go has no inheritance — child structs duplicate parent fields.
 * Polymorphic types use interface{} and type switches.
 *
 * Structural blocks emitted per type (in order):
 *   1. Description comment
 *   2. Struct definition
 *   3. Load function
 *   4. Save method
 *   5. ToJSON method
 *   6. ToYAML method
 *   7. FromJSON function
 *   8. FromYAML function
