5b45bcc16d 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.
