mineracks 9d380f5013 Initial import: CKBunker HSM validation harness
WebSocket client + CLI harness + pytest suite that exercises each axis of
a CKBunker + Coldcard Mk4 policy and asserts the expected outcomes, including
the critical negative test that a large PSBT without TOTP is rejected with
a specific 'rule #1: need user(s) confirmation' reason.

Configuration via .env / YAML / CLI flags, two pre-crafted test PSBTs as
fixtures (generation guide in fixtures/README.md), dashboard counter
scraper as sanity check, design rationale in docs/.

"""The critical negative test: a transaction that exceeds the auto-approve
cap must be *rejected* by the Coldcard when TOTP is absent.
If this test passes, your policy is doing its job. If it fails by reporting
SIGNED, stop everything and review the policy on-device — you are running
with no 2FA gate on Rule #1-sized spends.
