 mcp: preserve single-request batch responses (#1214) 
## What does this PR do?

Preserve JSON-RPC batch response arrays when a batch contains a single
request.

## Why is this needed?

A single-request legacy batch must be returned as a one-element JSON
array, but the JSON response path currently unwraps it into a single
JSON object.

## Changes

- Preserve the original batch state on the logical stream
- Keep single-request batch responses as arrays
- Add a regression test for legacy initialization batches

## Testing

- `go test ./mcp -count=1`
- `go test ./... -count=1`
- `git diff --check`

Fixes #1211
