chore(logs): drop hard-coded temporary probe logs

Remove three one-off investigation aids pinned to one seed/coordinate:
- [VoxelForgeExplore][TemporaryShaftConnectors] in the shaft connector
  op's Eval (a thread_local flag + coordinate test in the density path);
- [VoxelForgeExplore][TemporaryVerticalLanding] in the vertical-shaft
  landing search (seed 14, bottom Z -736 only);
- [VoxelForgeExplore][TemporaryShaftProbe] in the explore commandlet walk
  mode (seed 14 VerticalShafts only; its own comment said it would be
  removed once the seam was fixed).

No tool, test or script matches these tags (Tools/*.ps1 only parse
[VoxelForgeExplore][OwnerAssets] under that prefix). The probe's density
reads were log-only, so generated geometry and reports are unchanged.
All cvar-gated diagnostics and test result lines are kept.
