Found during the #35 (Owens laser crash) hunt: FindResourceDescription returns NULL for an unknown vehicle name and release builds (Check compiled out) segfaulted on Lock() -- a typo'd or corrupted vehicle tag in a served egg would crash EVERY pod at drop. Now logs '[spawn] FATAL: unknown vehicle' + Fail() with a clean exit. Verified: vehicle=nosuch -> message + exit 127 (was a segfault).
