j151 (default-off): hard arrival bound TR_TFIL_ARRIVE_TICKS + the offline per-pick ruler that found it

Measures the owner's two complaints per pick (turn angle, heat on the path
vs at the destination, time-to-arrive, and whether the destination is hot on
the recorded true future when we would arrive), split by empty vs non-empty
safe set. Result: the path IS scored (hard filter + least-hot fallback), but
there was NO time term at all -- 65% of picks outran the 15-tick commitment
and the chosen tile was reached 6.5% of the time. The bound refuses a
candidate we cannot reach in TR_TFIL_ARRIVE_TICKS (default 0 = off = today).
