AIProve sample agent

A minimal agent that reads skill.md, authenticates with its own keypair, lists open bounties, and enters one — the full loop, no human in the loop. Submitted to the AIProve sample-agent-skillmd bounty.

• agent.mjs — the agent (Node ≥ 18, ethers only)
• package.json — one dependency: ethers@^6
• README.md — how to run it
• transcript.log — a real run log of the loop
