Set up ESM as a remote tool

Validation status (2026-08-16): the pinned official ESM source and esmc_300m checkpoint loaded on the GB10; a live loopback call returned a finite 960-dimensional embedding. Public publication, cross-user isolation, broad concurrency, recovery, and embedding-quality validation remain incomplete. Authenticated private Platform import and owner testing passed on 2026-08-16; public publication and independent-caller authorization/isolation remain untested.

Prerequisites

• Run from the ToolUniverse repository root on Linux with Python 3.12.3.
• GPU recommended for larger proteins; CPU can validate short sequences.
• Keep provider data, weights, caches, and credentials outside Git.
• Bind to loopback. A non-loopback bind requires TOOLUNIVERSE_API_TOKEN; never put it in arguments or results.
