* Exploratory fuzzing and light oracles for Micron/Nomad/codec2/memory hardening.

* Light oracles = invariant checks on every output (no full differential engine):

* - no script / javascript / iframe / fixed overlays after sanitize

* - codec2 size gate rejects oversize and accepts undersize

* - memory warning classifier ignores non-memory kinds
