Subject: [PATCH] fix: add btcAddress to register and heartbeat curl examples
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BIP-322 signature verification requires btcAddress in the POST body
for both /api/register and /api/heartbeat. Add the field to all four
curl examples (SKILL.md and daemon/loop.md in both root and template).

Registration sign message already uses "Bitcoin will be the currency
of AIs" — confirmed correct, no change needed.
