Rename Sysadmin Session Closer Agent to Finish Up Agent

Renamed the agent from 'sysadmin-session-closer' to 'finish-up' and added VPS hostname functionality to session summary filenames.

Changes:
- Renamed agent file: agents/sysadmin-session-closer.md → agents/finish-up.md
- Updated agent version to 1.1.0
- Modified agent to include VPS hostname in session summary filenames
  - Session summaries now use format: [PROJECT_NAME]-[HOSTNAME]-session-summary.md
  - Hostname is auto-detected using `hostname` command
- Updated all documentation references:
  - README.md, QUICK-START.md, agents/README.md
  - scripts/README.md, scripts/bootstrap-agents.sh, scripts/init-project.sh
- Improved agent description to mention VPS hostname functionality

Repository: http://100.120.125.113:3000/pdm/homelab-agents
Next Session Focus: Test the renamed agent on a VPS project to verify hostname detection works correctly
