/**
 * TypeScript code emitter — Declaration IR → TypeScript source code.
 *
 * Replaces `file.ts.njk` (~414 lines of Nunjucks templates)
 * with a typed TypeScript function that walks the FileDecl tree.
 *
 * The emitter produces correctly-formatted TypeScript code using modern
 * class patterns with `Partial<T>` constructors. Output is post-processed
 * by prettier + eslint, so exact whitespace is not critical.
 *
 * Structural blocks emitted (in order):
 *   1. Header comment (auto-generated warning)
 *   2. Imports (LoadContext/SaveContext, referenced types)
 *   3. For each type in the file:
 *      a. [abstract] class definition with extends
 *      b. shorthandProperty static ClassVar
 *      c. Field declarations with type annotations + defaults
 *      d. Constructor with Partial<T>
 *      e. //#region Load Methods
 *         - load() static method
 *         - loadKind() for polymorphic dispatch (private static)
 *         - Collection helpers (loadX / saveX)
 *      f. //#endregion
 *      g. //#region Save Methods
 *         - save() instance method
 *         - toYaml() / toJson()
 *         - fromJson() / fromYaml() static methods
 *      h. //#endregion
 *      i. Factory static methods
 *      j. Method stubs (as comments)
