 * Generates an OpenAPI 3.1 specification from an `HttpApi`.
 *
 * **When to use**
 *
 * Use when you need a programmatic OpenAPI document for an API definition.
 *
 * **Details**
 *
 * This function takes an `HttpApi` instance, which defines a structured API,
 * and generates an OpenAPI Specification (`OpenAPISpec`). The resulting spec
 * adheres to the OpenAPI 3.1.0 standard and includes detailed metadata such as
 * paths, operations, security schemes, and components. The function processes
 * the API's annotations, middleware, groups, and endpoints to build a complete
 * and accurate representation of the API in OpenAPI format.
 *
 * The function also deduplicates schemas, applies transformations, and
 * integrates annotations like descriptions, summaries, external documentation,
 * and overrides. The optional reference policy receives canonical JSON encoded
 * ASTs and controls which schemas are extracted into components. By default, only candidates with resolved identifiers
 * become references; anonymous non-recursive schemas remain inline. The optional `includeAnnotationKey` predicate selects
 * custom schema annotation keys, such as `x-*` vendor extensions, to include in the generated schemas.
 *
 * **Gotchas**
 *
 * Cached results are keyed by both the `HttpApi` instance and the identity of the options object. Reuse the same immutable
 * options object to reuse a cached result; mutating an options object after its first use does not invalidate the cached
 * specification. Each call returns a copy of the cached specification.
