COSOM session files & optional assists

The portable chosen-file workflow uses the shared SNES session format, copied from its frozen 1.0.0 source. It validates game/core identity and checksums, and confirms local writes after close and readback. A session file is an emulator snapshot, separate from PS1 memory cards.

Cheat and story checks are separate browser additions. Every cheat starts off; the observer reads copied native snapshots. Sources, exact hashes and test scope are recorded in the accompanying manifests.
