chore(pkg): add package.json (name/version/peerDeps/exports/sideEffects)

Libs shipped as bare source with no manifest — consumable only via per-app
vite/tsconfig alias surgery, no version contract, no tree-shaking signal.
Add a minimal package.json matching the @crema/content-ui template: entry +
exports map, declared peerDependencies, sideEffects:false. Mechanical, no
code change. Frontend audit 2026-06-20, rank 2.
