Adds configuration to build and run this repository in cloud development environments.

• install: Node 22 via NodeSource, pnpm via corepack, pnpm install --frozen-lockfile, pnpm build
• prepare: fast idempotent pnpm install --frozen-lockfile
• env: non-interactive corepack

Verified by running the install command to exit 0 in a clean Ubuntu 24.04 sandbox.
