Adjusts the SDK TypeScript build so outputs land in dist/ (instead of dist/src) by tweaking tsconfig settings for better monorepo compatibility, and updates .gitignore to ignore the generated tsconfig.tsbuildinfo cache file. This should fix the referenced build/layout issue and make published artifacts align with expected paths, but it changes output structure and adds a new ignored build cache—so downstream tooling or scripts that assume the old dist/src layout should be verified, and ignoring the tsbuildinfo file shouldn’t mask unexpected build state problems in CI.
