jif 789c72dcf6 Avoid shifting bytes in streaming output buffers (#36194) ...

## Why

Removing each decoded prefix from a `Vec` shifts all remaining bytes. Repeating
that work is costly for streams containing many invalid UTF-8 bytes or many
framed messages in one relay record.

## What changed

- Buffer unified exec output in a `VecDeque` and use UTF-8 error offsets to
  consume the largest valid prefix while continuing to make progress on invalid
  input.
- Buffer Noise relay messages in `BytesMut` and advance past decoded frames
  without moving the remaining bytes.

## Testing

Added regression coverage for valid data surrounding invalid UTF-8, front
consumption without shifting, and reassembling many JSON-RPC messages from one
record.
