chore(dev): install and wire react-grab

react-grab lets you point at any DOM element on the page and press
Cmd+C to copy the file name, React component, and HTML source — then
paste straight into a coding agent (Claude Code, Cursor, etc.) for
much higher-fidelity context.

Wiring (auto-detected by `npx grab@latest init --force`): a Next
<Script> tag in src/app/layout.tsx that loads the bundle from unpkg
in development only. Production builds skip the script entirely so
no extra weight ships to end users.
