wip(assembler): round L14 -- far-LOD cost counted; no exact-output lever above 3% (opt-in counters)

Browse Source 
Plain W12 far work: LOD6 2.59, LOD8 2.05, LOD4 1.57, LOD5 1.41, LOD7 1.16 worker-s. Ground/cap
refinement ~3.95 worker-s and LOD6 connector repair 1.40 worker-s (82% uncached formula calls)
build visible geometry; no bit-identical reduction proved. Adds opt-in far-shell column counters
(reviewed: no cost when off, interleaved 1.429 vs 1.419 s). All hashes, the crossing hash and route
parity are unchanged.
