/**
 * Build an HTTPRequest JSON shape for the confidential-http capability.
 *
 * The proto defines `oneof body { string body_string = 3; bytes body_bytes = 8 }`,
 * so the JSON wire keys are `bodyString` / `bodyBytes` — never plain `body`.
 * Three mutually-exclusive ways to set the body, in order of preference:
 *
 *   - `body`        ergonomic; coerces by runtime type:
 *                     - `string`     -> bodyString (verbatim)
 *                     - `Uint8Array` -> bodyBytes (base64)
 *                     - object       -> JSON.stringify -> bodyString
 *                                       (bigints as strings)
 *   - `bodyString`  pass-through to the canonical proto field
 *   - `bodyBytes`   `Uint8Array` is base64-encoded; a `string` is treated as
 *                   already-encoded base64 and passed through verbatim
 *
 * Supplying more than one of these fields throws — the underlying proto is a
 * oneof, so the call would otherwise be ambiguous.
 *
 * Headers can be passed in two ways:
 *   - `headers`: flat record with single or repeated values, mapped onto the
 *     `multiHeaders` shape under the hood.
 *   - `multiHeaders`: native proto shape `{ [name]: { values: string[] } }` —
 *     useful when forwarding headers already in canonical form.
 *
 * If both are supplied, `multiHeaders` is applied first and `headers` entries
 * merge on top per-name (replacing the values list for that name).
