v0.2.0

Initial release of the Metreeca Tile minimalist model-driven UI toolkit, superseding the legacy @metreeca/tile 4.x
line: a design system published as CSS tokens and base rules, with Preact bindings wiring components to headless
@metreeca/core state and @metreeca/http clients. @metreeca/tile-lens and @metreeca/tile-form claim their
package names ahead of the linked data views and forms they will carry.

• @metreeca/tile — design system tokens (colours, palettes, typography, spacings, scalings, borders, elevations,
  layers, motions, opacities, viewports, visuals), base markup rules, data-theme colour scheme pinning and the
  css() / css.var() helpers
• @metreeca/tile-data — shared faults, shared fetch client, headless component state and client-side routing
• @metreeca/tile-cell — button, fault, icons, link, logo and note widgets
• @metreeca/tile-hive — shell, styled area and tabbed panel containers
• @metreeca/tile-lens — linked data selection state
• @metreeca/tile-form — placeholder for linked data forms
