2-phase design for `pnpm turbo gen core-ui-component`. Prompts for tier
(atom/molecule/organism) + name (PascalCase) and emits the established
4-file component pattern (component.tsx, component.stories.tsx,
component.test.tsx, index.ts) into the matching `packages/core-ui/src/<tier>s/`
folder. Splices the new export into the tier barrel via `// <gen:<tier>s>`
anchors.
Phase A adds the anchors to the core-ui template's three tier barrels and
regenerates the byte-identical reconstruction snapshot. Phase B ships the
generator, templates, tests, and docs. Refuses to run if core-ui isn't
scaffolded; doesn't touch Storybook config (existing stories glob covers
new component stories).
