fix(types): remove DOM type dependencies from ClientResponse and request method (#4768)

Remove `extends globalThis.Response` from ClientResponse interface and
replace `RequestInfo | URL` with `Request | string | URL` in the
Hono.request() method signature.

These changes make hono's type declarations self-contained without
requiring DOM lib types (lib.dom.d.ts), enabling projects that use
`skipLibCheck: false` in non-DOM environments (Bun, Node without DOM
lib) to compile without errors.

Changes:

- ClientResponse: Remove `extends globalThis.Response`, add
  `redirected`, `type`, and `bytes()` properties inline so the
  interface remains structurally compatible with Response
- Hono.request(): Replace `RequestInfo | URL` with
  `Request | string | URL` (semantically identical since
  RequestInfo = Request | string in DOM lib)
