Claude (sandbox) d5b6a8f66f feat(causal): pipeline demo modes for the reserve-shortfall experiment

SMARM_CAUSAL_MODE selects the reserve stage's guard placement:
work (default, unchanged) | wide (guard over recv+work+send, the whole
serialized per-item path) | occupancy (no experiments; per-segment
timing of reserve's loop at baseline, reporting the unguarded
remainder δ and the impact ceiling it implies).

Discriminates the two candidate explanations for the demo's +84-vs-+100
@50% shortfall: physical recv/send time outside the guard (occupancy
sees δ≈30µs, wide recovers ~2x) vs. injection-side credit loss
(occupancy sees δ≈0, wide caps at ~+84 too — guard cadence identical).
