Subject: [PATCH 1/3] [DEMO] Scope perf-smoke matrix to Cartpole +
 Velocity-Flat-G1

Trim the benchmark matrix to the two well-baselined demo tasks (physx +
newton each) for a fast, clean four-cell verdict table. Demo only; not for
merge.

Subject: [PATCH 2/3] [DEMO] Reintroduce tomllib import env regression
 (hard_failure)

Simulate the environment-regression class where a PR adds 'import tomllib'
(stdlib only on Python 3.11+) while the benchmark image still ran Python
3.10, crashing every task at import before any perf data is produced. The
perf gate then reports HARD_FAILURE for all cells (no FPS to compare).

The perf-gate image is Python 3.11, so the failure is reproduced
deterministically with an explicit ModuleNotFoundError guard. Demo only;
not for merge.

Subject: [PATCH 3/3] [DEMO] Add Factory-GearMesh (physx) to demo matrix

Include the newly-seeded Factory-GearMesh task so the HARD_FAILURE table
covers a third task as well. Demo only; not for merge.
