fix: add --force-reinstall to agent installation to fix pkg_resources metadata

When installing agent in editable mode, the entry point script's __requires__
metadata may not correctly reflect installed dependencies, causing runtime
DistributionNotFound errors for zope.interface and zope.event.

Adding --force-reinstall ensures:
- All dependencies are reinstalled correctly
- Entry point scripts are regenerated with correct metadata
- pkg_resources.WorkingSet properly registers all packages

This is a minimal fix that adds only one line to resolve the issue.
