Set up cell2location as a remote tool

Validation status (2026-08-16): the scientific environment, GB10 execution, loopback discovery, and a bounded synthetic single-cell/spatial deconvolution call passed with finite abundance output. Public publication, cross-user isolation, representative accuracy, broad concurrency, and recovery remain incomplete; keep this deployment private. 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 production posterior fitting; CPU only for tiny tests.
• 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.

Run the standard-library contract check before downloading large dependencies:
