Update README to v2.2 with multi-panel support accomplishments

MAJOR UPDATE: v2.1 → v2.2

Added new section highlighting multi-panel architecture completion:
- Full cPanel, InterWorx, and Plesk support (all production ready)
- 38/38 modules refactored (100% complete)
- Automated validation scripts (13 tests InterWorx, 15 tests Plesk)
- All critical paths verified on production systems

New section on System Detection & Abstraction:
- Automatic control panel detection
- Multi-panel user/domain management abstraction
- Dynamic log discovery for all panel types
- Zero hardcoded paths - all detection-based

Updated existing sections to reflect multi-panel capabilities:
- Website Diagnostics now explicitly multi-panel
- Security tools updated with multi-panel support
- Core Infrastructure highlights production validation

Changed tagline to reflect multi-panel support capabilities.

This represents the completion of the largest refactoring effort
to date, bringing full multi-panel support to the entire toolkit.
