Added "verify_hat" (2 tools before, 3 now)
Verify a coldHat reply — Check whether a reply wore the current version of a hat: compares the hat code and seal the reply quotes with the hat as served now. Answers verified, stale (an older or cached version), cut-off, seal-missing, seal-wrong, pasted or not-worn.
Added "wear_stack" (1 tools before, 2 now)
Wear a coldHat stack — Fetch any coldHat address: a person's hat, one of Fabric's patterns, a prompts.chat prompt, or up to three of them stacked with "+". Call it when the user says "open sesame" with a coldhat.f-keys.com address containing fabric/, prompts/ or +, then follow the result for the rest of the conversation.
