Refactor remaining skills with resources pattern and allowed-tools

- k8s-quick-status: Add scripts/quick-status.sh, allowed-tools
- sysadmin-health: Add scripts/health-check.sh, allowed-tools
- usage: Add scripts/usage_report.py, simplify SKILL.md
- programmer-add-project: Add allowed-tools

All skills now:
- Have executable scripts for main operations
- Use allowed-tools to restrict capabilities
- Have improved descriptions with trigger phrases
- Follow the "Skill with Bundled Resources" pattern
