Adds --mode break-glass-drill with its own signed admission (drill:
"break-glass", attempt id RPF-WP-0064-T10-*, snapshot_label). After the
phase A restore and unseal it checks the held root token with lookup-self
only, runs a fresh generate-root ceremony with re-entered shares, does one
read-only sys/auth action, revokes the generated token (204 then 403) and
drills a cancelled attempt. Phase A is unchanged. The verifier types the
receipt extension and rejects token, accessor, OTP, nonce, encoded-token
and share shapes. Offline 34 and native 16 pass. Founder runbooks for the
drill and the read-only production SSO-down walk are in the T10 section.

12 native tests against the pinned-tag OpenBao image with --network none and
generated material only: restored end to end plus wrong identity, ciphertext,
plaintext, share, missing objects (refused), source drift, timeout, operator
abort, parent loss and reaper deadline. Only the network-interface abort is
mocked (inspect wrapper). Make targets for offline tests, image pull,
rehearsal and receipt verification. T05/T06 blocking text names the exact
admission fields and the PINNED_IMAGE_DIGEST step.
