feat: design system v1.0.0 — reconcile tokens from cross-repo audit

Extracted real production usage from 8 KDC repos and consolidated the
consensus (kdcsurveyadd / kdcvault / kdc_void_planner) into the canonical
design.md + tokens.

Highlights:
- brand.ink #000000 -> #1A1530 (purple-tinted, matches real usage)
- brand.canvas #F5F4F0 -> #F7F4ED (warm)
- neutral ramp rebuilt around ink (purple-tinted, not cold slate)
- semantic palette retuned for warm canvas + soft tints
- elevation shadows retinted with brand-ink rgb
- new accent.gold (product) and accent.mint (marketing) tokens
- real themes/light, themes/dark, themes/high-contrast
- fleshed out every component + foundation README
- docs/consolidation-2026-05.md captures the full audit + drift inventory

 ## Status
 
-Version: **beta**. Tokens and components are still settling — expect breaking changes.
+Version: **1.0.0** (reconciled 2026-05-17). Canonical palette and components match the production implementations in `kdcsurveyadd`, `kdcvault`, and `kdc_void_planner`. See [`docs/consolidation-2026-05.md`](./docs/consolidation-2026-05.md) for the cross-repo audit and outstanding drift in `kdcdiary` / `kdctracker` / `kdcdocs` / `kdcmapper`.
