Migrate internal module imports to unified package path.

Replaced legacy `*.orly` module imports with `next.orly.dev/pkg` paths across the codebase for consistency. Removed legacy `go.mod` files from sub-packages, consolidating dependency management. Added Dockerfiles and configurations for benchmarking environments.
