feat: Add tooling sync mechanism for multi-module consistency

[kojiromike]

Problem

As the number of OpenEMR modules grows, keeping common tooling (pre-commit config, GitHub workflows, phpstan/rector configs, etc.) synchronized across all modules becomes increasingly difficult and error-prone.

Desired Outcome

A mechanism to propagate tooling updates from this template to existing modules, ideally with:

• Ability to update existing modules when the template changes
• Tracking of which template version a module was created from
• Handling of module-specific customizations vs common tooling

Options to Consider

• Copier - Template engine with built-in update support
• Sync script - Simple file copy approach
• GitHub reusable workflows - For CI portion only
