fix: generate Prisma client locally to fix CI symlink failures

The db:generate script used ln -sfn to symlink generated Prisma
files into node_modules/@prisma/client, which fails in CI because
pnpm's virtual store is read-only.

Changes:
- Configure Prisma to output generated client to src/generated/client
- Update all imports from @prisma/client to local generated path
- Copy generated files to dist/ post-build for runtime resolution
- Add db:generate step before build:packages in CI lint job
- Add DATABASE_URL env to db:generate steps in CI
- Ignore generated/ directory in git
