Explanation

The following changes extend c26899a:

• eth-json-rpc-middleware
  • There were some unnecessary type assertions in inflight-cache.ts that have been removed.
• message-manager
  • The rename of OriginalRequest introduced a breaking change. We don't strictly need to do this now, so we keep the old type around for backward compatibility.
• network-controller
  • The changelog has been updated to mention that a new export was added, and to detail more changes to createWalletMiddleware.
  • The signatures of request in RpcServiceRequestable and RpcServiceChain were updated to match the same method in RpcService (and the change to RpcServiceRequestable was marked as breaking).

Progresses #6327.

Adds providerAsMiddlewareV2, deprecates OriginalRequest, and updates RPC request types to require Readonly/frozen JSON-RPC requests; tightens inflight-cache typings.

  • Added: providerAsMiddlewareV2 to convert an InternalProvider to v2 middleware.
  • Changed: Changelog clarifies migration to JsonRpcEngineV2 and updated createWalletMiddleware hook signatures.
  • Tighten inflight-cache types: use Readonly<Json> for results, unknown for errors, and remove unnecessary casts.
• message-manager:
  • Changed/Deprecated: Keep OriginalRequest as a deprecated alias of MessageRequest in code and changelog.
• network-controller:
  • BREAKING: request signatures in RpcServiceRequestable/RpcServiceChain now accept Readonly<JsonRpcRequest<...>> (frozen requests); reflected in changelog.
