Phase 13.58.ADF: taxonomy + matrix for LAZY.subframe_draw (count-lock 51->52)

Subframe-column lazy draw (single-level A.col + nested/recursive A.B.col), shipped with
tests in the preceding commits, was not represented in the taxonomy. Add it as
LAZY.subframe_draw (3 test functions), bump the Phase 13.56 post-audit count-lock 51->52,
and regenerate docs/CAPABILITY_MATRIX.md (FM#13: regenerated, not hand-edited).

Matrix now: 52 features; LAZY.subframe_draw verified (3/3), LAZY.timeseries_draw verified
(36/37, gallery skipped). Full run 1738P/8F/1E -- the 8F/1E are the documented pre-existing
set (K1/K2 vector-draw, RDF friend-trees x3, backend I2_6, compression I4_2/I4_3, schema
serialization ERROR); no regression.
