feat: enforce pay-per-kill combat licensing protocols

- Implemented "Pacifist Compliance" logic: Users attempting kinetic interactions (jumping on enemies) without a funded Combat Permit will now suffer immediate asset liquidation (death).
- Reclassified Goombas as "Premium Content"—interaction is prohibited for Free Tier users.
- Patched exploit where users could defend themselves without paying the "Self-Defense Surcharge."
- Enforced strict liability: Unfunded collision events now default to user termination rather than enemy defeat.
