Contact event and announcement gates

RE-716. Reproduce with python3 scripts/analyze_qvm_contact_announcement.py; check with python3 scripts/test_qvm_contact_announcement.py. The machine report retains source identity and bounded fixtures.

Actual292833–292916 bypasses events to293373 when caller148 is zero or scalar56 compares equal to float zero. Negative explicit scalar fixtures still pass this gate. Announcement7259 is conditional on global34081316 and clear victim client220 bit16384 plus entity552 bit16. Its eight arguments are original format97459, target ID, attacker ID, location, weapon, attacker client504 name pointer, victim client504 name pointer, and original3704+4×location label pointer. The request is captured without executing formatting/output effects. Announcement suppression does not suppress the event continuation at292917. No event allocation or health damage occurs in this range.

No original executable/full QVM/native collision/physics/rendering executes. Native responses and legal input domains are supplied or unverified where stated; full runtime/macOS/Linux Rust/Bevy/Solari gameplay remains open.
