Adds setup.browser.ts with fake-indexeddb, a fetch polyfill that points sql.js WASM and loot-core's data-file-index fetches at on-disk files, and wires the browser Vite config to use jsdom. The shared integration spec now gates the full CRUD roundtrip behind __API_FULL_SUITE__ (set only in Node) because absurd-sql's worker + SharedArrayBuffer requirement is not met under jsdom; the browser smoke test verifies that init returns a usable handle. Full-flow browser coverage moves to the playground app in the next phase. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
