E2B Files

Patch Changes

• 48d24ac: - Fixed Sandbox.files.read / AsyncSandbox.files.read failing at random for files over ~500 KB (and always for a few MB) with httpx.ReadError ... too_many_data_frames. File downloads now go over HTTP/1.1 regardless of http_version, as h2 closed HTTP/2 connections after receiving 100 empty DATA frames, which the sandbox proxy sends throughout file responses.
• 1ad3f76: Template builds hash copy() files in 1 MB chunks instead of reading each file fully into memory, cutting peak memory for large files. Hashes are unchanged, so existing build caches stay valid.
