fix: apply push-options to patch series generation

The title and description push-options were previously only applied to PR
creation but not to patch series generation. When force-pushing to update
an existing patch series, the custom title and description were ignored.

This change passes the title_description parameter to the patch generation
function, allowing users to customize patch series cover letters via:
  git push --force --push-option=title="Title" \
    --push-option=description="Description" origin branch

Includes integration test for force-pushing patches with custom cover letter.
