Release v0.5.1: Fixed z.record() schema display

[0.5.1] - 2026-01-28

Fixed

• z.record() schema display - Fixed issue where z.record(z.string(), z.string()) and other
  record schemas were incorrectly displayed as {} in both TypeScript types and JSON examples
  • Now properly generates Record<string, string> TypeScript notation
  • Generates sample JSON examples like { "key": "string" }
  • Supports all record value types (primitives, objects, arrays, etc.)
  • Root cause: Zod's toJSONSchema() converts records using additionalProperties instead of
    properties, which wasn't being handled
