/**
 * Decide which eth proof-owner key `run_proof` should sign with, BEFORE
 * calling it. The key is a raw 0x-hex Ethereum private key, resolved (no
 * `~/.reclaim` cache) from:
 *   1. `RECLAIM_PRIVATE_KEY` in the MCP env
 *   2. a `RECLAIM_PRIVATE_KEY=0x…` line in the project `.env`
 *   3. a file at `RECLAIM_PRIVATE_KEY_FILE` holding the raw hex
 *   4. none → ask the dev to generate (issue_credentials) or provide one
 *      (import_credentials), then call again.
 * Never returns the private key — only the derived address.
