/**
 * Framework-Agnostic Error Response Utilities
 *
 * Provides standardized error response data objects (not Response/NextResponse wrappers).
 * These functions return plain data objects that can be wrapped by framework-specific
 * response utilities (NextResponse.json, new Response, etc.).
 *
 * Use these functions to create error response data, then wrap in your framework's
 * response type:
 * - Next.js: `NextResponse.json(createErrorResponseData(...), { status: 400 })`
 * - Standard: `new Response(JSON.stringify(createErrorResponseData(...)), { status: 400 })`
