feat(design-data): excludeFromLegacy token field + button corner-radius fix

+
+Add an `excludeFromLegacy` token field so new tokens without Tokens Studio
+precedent can be authored directly in design-data without publishing to the
+legacy flat-key mirror, and use it to fix SPEC-027 dangling `button.json`
+corner-radius bindings (bead spectrum-design-data-vpk.1).
+
+- **packages/design-data-spec/schemas/token.schema.json**: new optional
+  `excludeFromLegacy: boolean` on both token shapes.
+- **sdk/core/src/legacy.rs**: `convert_array` skips any token with
+  `excludeFromLegacy: true` before it's grouped into legacy output.
+- **packages/design-data/tokens/layout.tokens.json**: add
+  `button`/`corner-radius` tokens for `small`/`medium`/`large`/`extra-large`
+  (desktop + mobile), literal pixel values derived from
+  `component-height-*` ÷ 2, marked `excludeFromLegacy` — no legacy output
+  change.
+- **packages/design-data/components/button.json**: rebind the three
+  corner-radius entries from the non-existent literal strings
+  `corner-radius-button-{small,large,extra-large}` to the new tokens'
+  resolved key `button-corner-radius-{small,large,extra-large}`.
