Add comprehensive Docker test environment for installation validation

Add complete Docker testing infrastructure to validate all 3 installation methods

Features:
- Dockerfile: Ubuntu 22.04 with Node.js 20, Python 3, prerequisites
- docker-compose.yml: Orchestrate 3 test containers + verification
- Test suite with 5 scripts:
  * common.sh: Shared utilities and verification functions
  * test-interactive-install.sh: Test Option 2 (interactive installer)
  * test-master-prompt-install.sh: Test Option 1 (master prompt)
  * test-manual-install.sh: Test Option 3 (manual installation)
  * verify-all-installations.sh: Master verification with report generation
- run-tests.sh: Quick start script for easy test execution

What Gets Tested:
✓ Prerequisites (Node.js, npm, Python, Git, jq)
✓ Claude Code installation and version
✓ Settings files (settings.json, settings.local.json)
✓ 38 agents across 8 departments
✓ MCP tools (@z_ai/mcp-server, @z_ai/coding-helper, llm-tldr)
✓ UI/UX Pro Max skill
✓ Ralph CLI (optional, can be enabled)

Test Results:
- Saved to docker/test-env/test-results/
- Detailed logs for each test method
- Component verification counts
- Comprehensive final report with pass/fail status

Usage:
cd docker/test-env
./run-tests.sh

Or manually:
docker-compose up verify-all
