fix #270 closeout: strip investigation probes; close the issue

User-verified: casting fixed (exhaustion-edge gate) and monster attack
animations restored (spawn settle placement + lost-cell retry). Final
session evidence: 14/15 spawn settles grounded; Falling-refusal spam
collapsed 2,954 -> 15 transient pre-settle lines.

Strips the [UM-ACT]/[MT-FAIL]/[SPAWN-PLACE]/[remote-edge] probes, the
MotionInterpreter.DiagnosticGuid plumbing, and the two throwaway probe
tests (motion-table attack sweep, vitae color dump - both findings are
recorded in ISSUES/research). Complete Release suite: 10,030 passed /
5 skips / 0 failures.
