Add package.json (name evidence-anchor, exports . and ./pdf, scripts
test/typecheck/lint), tsconfig.json (mirrors engine, DOM+jsx), vitest.config.ts
(happy-dom + react plugin), eslint.config.js (confines viewer libs to src/pdf/),
.nvmrc, and placeholder src entrypoints. Depends on @citation-evidence/engine
via sibling-checkout link only; no citation-evidence internals.
