Brandon Bennett 97d3f9f248 feat(admission): per-target lane-aware probes for combo/fusion fan-out (#9654 Wave 2)
Combo and fusion fan out N targets without ever consulting the adaptive-admission
layer: the parent request holds one lease, but each fan-out target is dispatched
unconditionally. With virtual lanes enabled (OMNIROUTE_CHAT_VIRTUAL_LANES=1), a
connection whose lane queue is full now SKIPS additional fan-out targets instead
of piling more queued work onto an already-congested session.

Adds PerTargetAdmissionHook (admission/types.ts) + createPerTargetAdmissionHook
factory (chatAdmission.ts): strictly non-blocking (maxWaitMs 0 - skip, never
queue), a no-op when virtual lanes are off, keyed to the parent tenantKey, and
release-on-admit so the probe is a capacity gate, not a hold.

Threaded through every parallel fan-out path:
- priority/weighted executeTarget + round-robin skip chains (combo.ts)
- fusion panel before fan-out (fusion.ts), judge fallback prefers survivors
- chaos parallel panel (autoCombo/chaosEngine.ts)
- tryFusionDispatch / tryRuntimeUnitDispatch / buildBaseOptions (dispatchPrelude.ts)
- chat.ts primary + safety-net redirect call sites

Snapshot exposes virtualLanes so the no-op gate is cheap and honest.

Tests: tests/unit/combo-lane-awareness-9654.test.ts (10 tests) - factory
semantics, priority/RR skip, fusion panel drop + all-skipped 503, no-hook
backward-compat baseline.
