Adam Perry @ OpenAI 875bf9209b Define exec-server protocol types for streamed file writes (#49778) ...

## What changed

- Add `read` and `replace` modes to `fs/open`, defaulting omitted modes to `read` for existing callers.
- Define `fs/writeBlock` request and response types for offset-based writes, with a maximum decoded chunk size of 1 MiB.
- Add the `fileWriteStreaming` capability, defaulting to `false`. Keep writable streams unsupported in the server and explicitly reject replacement opens.

## Testing

Add a protocol test verifying that legacy `fs/open` requests without a mode deserialize as read-only opens.
