build(extension-api): regenerate .d.ts for hygiene cleanup (wave-11)

Hand-patched mirror of foundation hygiene cleanup per AGENTS.md Rule 8
(Node 20 vs vite blocks `pnpm build` in this worktree):

- Strip HR-style section dividers
- Strip parenthetical decision archaeology
  ((per D5), (D-immutability-enforcement, Hybrid C),
  D-bootstrap-hooks (W6.P6.C), D-shell-ui-entrypoints (W6.P5.C), etc.)
  from per-export JSDoc — preserve AXIOMS.md §A1/A14/A15/A16/A12 refs
  and PHASE_A_EXCLUDED axiom blocks (functional content).
- Strip "W6.P8.UNMIGRATABLE / D-input-output-shape" todo refs.
- One stale `defineWidgetExtension` JSDoc example fixed (was already
  on foundation; rebase carried the fix through).

Mirrors foundation commit `ee0537fdb5`.

ADR: decisions/D-design-review-hygiene-cleanup.md
Zero published-surface change (no types added/removed/renamed).
