Pull Request Overview

This PR consolidates packaging by introducing optional dependencies for CPU/GPU optimization, adds preflight checks for required packages, and refactors the exception hierarchy. The changes enable more flexible installation options while ensuring proper error handling when dependencies are missing.

• Refactors exception hierarchy to use unified YarpBaseException base class
• Introduces preflight checks that validate required packages at import time
• Adds optional [cpu] and [gpu] package extras for targeted dependency installation

Running preflight checks at import time can slow down module imports and may cause import failures in environments where optional dependencies are intentionally not installed. Consider making the preflight checks optional or lazy-loaded to avoid blocking imports.

This line computes memory usage but doesn't assign the result to a variable or use it. The computation has no effect and should either be removed or assigned to a variable like final_memory as it was before.
