fix: separate client and server utilities to fix build error

Split lib/utils.ts into:
- lib/utils.ts: Client-safe utilities only (no Node.js imports)
- lib/project-utils.ts: Server-only utilities with Node.js imports

This fixes the Next.js build error where client components were importing
modules that contained Node.js dependencies (fs, path).

All tests pass and build succeeds.
