Adapt VPE's threading model with PinMAME 3.7

[freezy]

This PR stabilizes the PinMAME Unity integration around play mode lifecycle, cross-thread event dispatch, and shared-state handoff with the simulation thread. It also updates the PinMAME .NET dependency to 1.0.2, which uses the lastest PinMAME 3.7 beta.

Lifecycle and shutdown safety

• Added editor play mode lifecycle hook (PinMamePlayModeLifecycle) to coordinate deterministic PinMAME shutdown on play mode exit/editor quit.
• Hardened PinMameGamelogicEngine init/stop flow with start/stop gating and defensive unsubscribe/cleanup paths.
• Added StopForPlayModeExit() and improved OnDisable/OnDestroy/OnApplicationQuit handling to avoid stale callbacks and overlapping sessions.

Threading and performance instrumentation

• Added simulation-thread-facing interfaces:
  • IGamelogicInputThreading
  • IGamelogicTimeFence
  • IGamelogicCoilOutputFeed
  • IGamelogicSharedStateWriter
  • IGamelogicSharedStateApplier
  • IGamelogicPerformanceStats
• Added bounded/instrumented coil dispatch queue for simulation-thread consumption (TryDequeueCoilEvent), including backlog/drop warnings.
• Added callback-rate sampling and TryGetPerformanceStats.

Shared state publication / application

• Added shared state snapshots for coils/lamps/GI (WriteSharedState + ApplySharedState) with lock-protected state caches.
• Added de-duplication when applying lamp/GI state to avoid redundant updates.

Display / output handling improvements

• Reworked DMD frame copy path to direct byte copy and moved dispatch through main-thread queue wrapper.
• Switched DMD frame format reporting to DisplayFrameFormat.Dmd8.
• Added safer handling when display frames arrive before display buffers are registered.

Mech and misc fixes

• Fixed mech registration to use 1-based IDs and improved mech slot/max diagnostics.
• Cached mech name in PinMameMechComponent for clearer mapping error logs.
• Reduced hot-path logging in callback-heavy code paths.

Testing

• No automated test run was performed as part of this PR draft.
• Recommended validation:
  • Enter/exit play mode repeatedly with domain reload on/off.
  • Verify ROM start/stop reliability across sessions.
  • Verify DMD/segment updates and lamp/GI behavior.
  • Verify mech registration and coil dispatch behavior under load.
