Claude-skill-registry connector

Use when working with connector components - headers, sockets, wire-to-board, board-to-board connectors. Includes adding patterns, parsing connector MPNs, extracting pin count, pitch, and series information.

Adding New Connector Patterns

In the manufacturer handler's
```
initializePatterns()
```
:

registry.addPattern(ComponentType.CONNECTOR, "^NEWCON[0-9].*");
registry.addPattern(ComponentType.CONNECTOR_MANUFACTURER, "^NEWCON[0-9].*");

Add to
```
getSupportedTypes()
```
:

types.add(ComponentType.CONNECTOR);
types.add(ComponentType.CONNECTOR_MANUFACTURER);

Key Handler Methods

Extract Series

// Returns "61300" from Wurth header
handler.extractSeries("6130014021");

// Returns "43045" from Molex
handler.extractSeries("43045-0212");

Extract Pin Count

Most handlers can extract pin count from MPN for matching purposes.

Connector Handler Registry

There's also a specialized connector handler system in

connectors/

package:

```
ConnectorHandler
```
- Interface for connector-specific parsing
```
ConnectorHandlerRegistry
```
- Registry of connector handlers
```
TEConnectorHandler
```
- TE-specific parsing
```
WurthHeaderHandler
```
- Wurth header parsing
