CydandClaude Fable 5 570eb3aceb Single-binary race loop: menu -> race -> menu in one process 
WinMain now wraps the engine block in a loop: when a front-end-launched
mission ends under the local console, the setup screen comes back in the
same process instead of exiting (the arcade relaunch-per-mission model).
Replaces the CreateProcess self-respawn - required for Steam, where the
lobby and sockets must survive across races.

Second-cycle re-init crash fixed: d3d_OBJECT kept a static texture cache
keyed by filename, so race 2 got IDirect3DTexture9 pointers created on
race 1 destroyed device and died at first draw (DrawMesh AV). The cache
is now flushed in ~DPLRenderer before the device is released, and
ParticleEngine::Initialize drops particles left over from the previous
mission. Verified: three consecutive 30s races in one PID, each stopped
on time by the console with final scores collected.

Also: L4CONSOLELEN env override for test-length races, and the console
exposes MissionCompleted() for the loop.
