Fix bump-version workflow to publish correct package

When bumping cua-computer, the workflow was incorrectly publishing cua-agent
instead of cua-computer to PyPI. This was because the publish-agent job had a
condition that triggered for both cua-agent and cua-computer services.

Changes:
- Added computer_version output to capture the bumped computer version
- Changed publish-agent condition to only trigger for cua-agent service
- Added new publish-computer job that triggers for cua-computer service
- publish-computer job calls pypi-publish-computer.yml workflow

Now when bumping cua-computer:
- Bumps cua-computer version (as before)
- Also bumps cua-agent version to maintain dependency sync (as before)
- Publishes cua-computer to PyPI (fixed!)
- Does NOT publish cua-agent to PyPI (fixed!)
