feat(registry): hw write-on wave — hw-write-title block + control surfaces for the handwritten family (#3557)
* feat(registry): hw write-on wave — hw-write-title block + control surfaces for four hw components Adds hw-write-title (true glyph write-on: pen-traced Caveat via baked centerline masks, curvature-adaptive pen velocity, pen lifts, underline) and grows the handwritten family's four components with declared control surfaces (controls per the #3227 convention), the completed stroke-texture matrix (sharp + deterministic seeded spray — no feTurbulence), boil poses, and physically-derived arrival deformation (travel-aligned squash with volume preserved and spring recovery). Shipped single-path callers keep working unchanged (legacy helper bodies preserved; proven in a legacy wiring harness). Validated in one reference build: check clean, double-render framemd5 910/910 bit-identical, seek-shuffle 8/8, WCAG 2.3.1 flash-scan zero violations, physics burn-ins hand-recomputed.
