feat(admission): founder-signed trust and recovery-attempt admission (WP14 T02, WP15 T05)
All checks were successful
CI Smoke / host-smoke (push) Successful in 1s
CI Smoke / container-smoke (push) Successful in 2s

Reuse the gated-executor approval pattern: ssh-keygen -Y signatures over exact
bytes, verified against a runtime-unwritable allowed_signers anchor with a fixed
namespace per purpose. load_trust now refuses responder trust without a founder
admission; the KeyCape selector preflight gains --admission for one exact,
bounded recovery attempt. WP14 re-pointed to CUST-WP-0082-T06 and split founder
key admission into human-gated T04; WP15 T04 now requires the signed admission.
