Enhance LLM sandbox with persistent caching, helper scripts, and improved UX

Added comprehensive improvements to ClawdBox for better LLM agent experience:

- Tools: Added tree, tmux, htop, strace, file, less for enhanced debugging
- Python packages: httpie, pyyaml, requests, black, ipython pre-installed
- Persistent caching: pip/npm caches now survive container restarts
- Git config persistence: .gitconfig auto-links from /data volume
- Shell improvements: colored prompt, aliases (ll, k, dc), 10k line history
- Helper scripts: ConfigMap with disk-usage, health-check, clean-workspace, install-tools
- Environment variables: TERM, TZ, DEBIAN_FRONTEND for better compatibility
- Makefile: Common operations (build, deploy, logs, shell, health-check)
- Documentation: Comprehensive README with troubleshooting and workflows
