<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Optimizes file uploads in both JS and Python SDKs to avoid unnecessary
reads and add broader input support.
>
> - JS SDK: `Filesystem.write`/`writeFiles` now build a single
`FormData` using `toBlob` (new util) to pass
`string`/`ArrayBuffer`/`Blob`/`ReadableStream` without pre-reading;
updated tests add `ReadableStream` coverage
> - Python SDK (sync/async): `write_files` accepts `str`/`bytes`
directly, reads `TextIOBase`, and passes `IOBase` (binary) streams
through without reading; new tests cover `BytesIO` and `StringIO`
> - Changeset: patch bumps for `@e2b/python-sdk` and `e2b`
>
