Adds scripts/build-client.mjs which uses esbuild to compile TypeScript
files in src/scripts/client/ into minified IIFE bundles, then writes
them as TypeScript string-constant modules in src/scripts/generated/.
- Adds build:client npm script; wires it as prebuild and predev hooks
- Adds src/scripts/client/tsconfig.json with DOM lib for IDE support
- Excludes src/scripts/client/ from the root Worker tsconfig to avoid
DOM type conflicts with the Cloudflare Workers runtime types
