• feat: OpenAPI Cyclic Types support by @Nick-Lucas in #7283
• chore: Review stale skills (manual) by @github-actions[bot] in #7294

@trpc/openapi 11.16.0-alpha

Drops the type depth limit of 20, and significantly hardens cyclic-type support for both inference and Zod

Support zod.lazy via Standard Schema fallback

Strip symbols from output (no more __@asyncIterator@5456 symbols in output)

Add more comprehensive types for the OpenAPI doc from the official package (now a dependency) and apply some patches to these types because they're slightly outdated

Fixes several issues with gathering schema descriptions, such as consuming jsdoc comments from node_modules types
