v0.19.0

New Features

• Custom directives API — @json-render/core now supports custom directives via defineDirective, letting you declare new JSON shapes (like $format, $math) that resolve to computed values at render time. Directives compose naturally — nest $format over $math over $state and they resolve inside-out. All four renderers (React, Vue, Svelte, Solid) have built-in directive resolution (#279)
• @json-render/directives — New package shipping seven ready-made directives: $format (date, currency, number, percent via Intl), $math (add, subtract, multiply, divide, mod, min, max, round, floor, ceil, abs), $concat, $count, $truncate, $pluralize, and $join. Also exports createI18nDirective for $t translation keys with {{param}} interpolation, and standardDirectives for one-line registration (#279)

Improvements

• Example READMEs — Added documentation to the chat, dashboard, game-engine, and no-ai examples (#277)
