/**
* Deno-specific RequestInit augmentation.
*
* Importing this module adds a typed `client` field to `MisinaOptions`
* via augmentation of `MisinaRuntimeOptions`. The value is passed
* through to Deno's `fetch` so a `Deno.HttpClient` (created via
* `Deno.createHttpClient(...)`) can route the request — useful for
* custom CA bundles, mTLS client identities, proxies, and HTTP/2
* pooling tweaks.
*
* @example
* ```ts
* import "misina/runtime/deno"
*
* const client = Deno.createHttpClient({ caCerts: [pem] })
* await api.get("/upstream", { client })
* ```
*
* Reference: https://docs.deno.com/api/deno/~/Deno.HttpClient
*/
/**
* Opaque shape for `Deno.HttpClient`. We don't type the full surface;
* the user gets the typed handle directly from `Deno.createHttpClient`
* and just hands it to misina, which forwards it as `init.client`.
