Fix tsconfig rootDir so dist output matches package.json main field

The db package's tsconfig included both src/ and drizzle.config.ts,
causing tsc to compute rootDir as the package root. Output went to
dist/src/index.js instead of dist/index.js, mismatching the main
field. Set explicit rootDir: ./src and remove drizzle.config.ts from
the build include.
