fix(qwen38flashnext): make layouts deterministic and use host services

Browse Source 
The gap-fill pass stopped on a 120 ms stopwatch and QWEN_* environment
variables switched strategies, so the same job could nest differently
with machine load or environment. Gap fill now stops after eight failed
insertion sweeps, and the switches are internal properties with the
old defaults. Part reading, work area, rotation angles, scoring and
result assembly now use the host APIs; its collision gate is unchanged.

Synthetic benchmark (5 jobs, salvage 0.5): all valid, cost 7660.01 ->
7572.05, time 839 -> 553 ms. Not yet calibrated on production-size jobs.
