profile: per-term legacy FI/TN sample profiler (L76); passage/support is ~75% of field time

Browse Source 
Opt-in at build time (VOXELFORGE_PROFILE_LEGACY_TERMS=1; compiled out by default, ~2% when on).
Per legacy sample: passage/support composer ~1.05 us vs primitive scan ~0.19 us, boundary
band ~0.06 us, noise ~0.01 us. Resolved-passage constants are cached at field binding
(arithmetic order unchanged); whole-view effect within noise. Per-tile hashes identical to L75
in all 24 compiler x worker x view comparisons; fast tier PASS; Linux UE host builds.
R40 researcher notes attached.
