v0.107.0: key-auth-first bridge + staged-secret wipe on escrow confirm

Key-auth-first: a KeyAuthProber seam lets the bridge skip consume+install
when the already-installed key still authenticates (pinned to the freshly
verified host key) — descriptor changes on provisioned guests no longer
loop on consume-404. Fingerprint verify still precedes everything.

Wipe-on-escrowed: confirm-escrow now calls the agent's new
DELETE /escrow/stage-secret (v0.78.0) best-effort, closing the hygiene gap
where a ceremony-less confirm left the staged password file behind.
