Node.js File Upload Round-Trip Integrity Test

Verifies that @composio/core can upload a file and download it back without corruption.

Why This Exists

This suite is meant to catch regressions where file content is altered during upload (for example, sending base64 text instead of raw bytes).

It performs a real round-trip:

Test	Description
Upload	Uploads a deterministic binary payload via `composio.files.upload()`
Download	Downloads the uploaded object back from storage
Integrity	Compares byte length and SHA-256 checksum

This suite requires a real API key.

If COMPOSIO_API_KEY is not set, the suite is skipped.

Docker with Node.js versions: current (as specified in .nvmrc).

This ensures the behavior is tested against specific Node.js versions independent of the developer's local setup.
