fix: set rootDir to src in tsconfig.build.json for consistent output

The NestJS build was outputting to dist/src/main.js instead of dist/main.js
due to TypeScript's automatic rootDir calculation. Explicit rootDir: "src"
ensures the output is always at dist/main.js.

Also remove the test-run debugging step from CI.
