Fix Docker tests to achieve 100% on 2/3 installation methods

Major fixes:
- Fixed Claude Code verification (was checking 'claude-code', now checks 'claude')
- Fixed volume mount paths (use absolute path /tmp/claude-repo for runtime)
- Fixed agents copy path (removed incorrect /agents/ subdirectory)
- Fixed critical agent paths (studio-coach in bonus/, not project-management)
- Added expect package for interactive installer automation
- Fixed test count aggregation to read from individual result files

Test Results (after fixes):
✅ Manual Installation: 27/27 passing (100%)
✅ Master Prompt Installation: 15/15 passing (100%)
⚠️  Interactive Installer: 7/13 passing (54% - expect automation issue)

Note: Interactive installer works fine for manual testing, just difficult
to automate with expect scripts due to prompt matching complexity.
