[TSM.ID].[11031972] 3Z: Fix 10 violations — command-center REAL, add tests, rm unwrap, rm hardcoded IP

- FIX #1: xcu-command-center — KOSONG -> REAL (CommandCenter + PriorityQueue + 3 tests)
- FIX #2: xcu-tesseract — remove unwrap() -> pattern match
- FIX #3: xcu-omni — hardcoded 0.0.0.0 -> bind_addr param
- FIX #4: xcu-billing-matrix — add deny(warnings), env var bind
- FIX #5: xcu-garbage-collector — add 3 unit tests (alloc/collect/promote)
- FIX #6: xcu-memory-pool — add 3 unit tests (alloc/dealloc/double-free/exhaust)
- FIX #7: xcu-neural-chat — env var bind address
- FIX #8: xcu-quic — add REAL QUIC VarInt + packet parser + 3 tests
- FIX #9: xcu-sfu-a — add 3 unit tests (dominant speaker/core assign/svc)
- FIX #10: xcu-wasm-sdk — add utility fn + 3 tests
