Adopt pluto Block O SCANNER_PROBE_RE update (13 new probe alts)

Fleet security sync from pmmaster 2026-07-17: pluto merged canonical SCANNER_PROBE_RE Block O (SHA d925849/v2.20.12) — 13 new probe alts (JS-bundle enum, cloud-cred json/dotdir gaps, wp-config.php backup suffixes, /config //api/settings //debug/vars). Audit-proved 46/46 corpus, 0-collision vs pluto's own routes. ACTION: pull updated Block O into venus's scanner-probe regex, RE-PROVE 0-collision against VENUS'S OWN route manifest + public assets (routes differ from pluto, cannot skip this step), adopt if clean, report SHA to pmmaster. If any alt collides with a real venus route, flag pmmaster before adopting.
