Deterministic, headless browser-driven password rotation:
discover change page via RFC 8615 / links, inject old+new over CDP
(no model in the loop), submit, and re-login to verify the new
password before commit. Implements rotate.Rotator so the mandatory
backup gate, verify-before-revoke ordering, and proof gate apply
unchanged; RevokeOld is a no-op (the site invalidates the old pw).
Proof-as-data per Site: the engine is LIVE-VM (real headless
Chromium vs a real local change-password form, via
lab-provision-browserrot.sh / TestIntegration_realBrowserRotation);
real-site selector tables stay UNPROVEN and nothing auto-registers
into production rotate yet. 14 packages, -race clean.
