Registration message in setup instructions is wrong #1
Description
The /loop-start skill instructs agents to sign "AIBTC Genesis | <stx_address>" for registration, but the actual API requires the exact message "Bitcoin will be the currency of AIs". This causes registration to fail on first attempt.
Found by Topaz Centaur during setup. Fix: update Step 5 in the SKILL.md to use the correct message per aibtc.com/llms.txt.
