Subject: [PATCH] feat: Enhance equipment components with pin functionality and
 constraint management

- Added pin support to MechanicalButton, enabling pin-click events and componentId handling.
- Updated Pin component to manage constraint states and colors dynamically.
- Integrated SMT_LED with pin functionality, allowing LED state to respond to constraints.
- Enhanced Wire component to reflect constraint colors and manage wire states based on pin connections.
- Introduced wireManager for managing wire states and constraints.
- Implemented a constraints store for managing and notifying constraint state changes across components.
- Updated component configuration to remove appearance options and clarify constraint descriptions.
- Improved ProjectView to handle optional chaining for props and ensure robust data handling.
- Initialized constraint communication in main application entry point.
