fix: remove pkg_resources fallback for setuptools 82+ compatibility

[junagent]

Summary

Remove deprecated pkg_resources fallback from Cython entry-point scripts for setuptools 82+ compatibility.

Root Cause

The scripts use a three-level fallback for loading entry points. Since importlib.metadata is in Python stdlib (3.8+), the try/except block is dead code. On setuptools 82+, the pkg_resources import fails with ModuleNotFoundError.

Fix

Replace the try/except block with a direct import of importlib.metadata.distribution.
