Migrate from CLI options to explicit `tsconfig.json`

This change makes it easier to use an explicit `lib` configuration and types, which resolves type issues resulting from subtle mismatches between implied type imports (e.g., some files importing `ReadableStream` from TS's built-in Web API types and others importing from Node.js's `streams/web`).
