Supported ComponentTypes

Known Handler Issues
1. Pattern Order Issues
Pattern ^ESP32.* may match before more specific patterns like ^ESP32-S3.*.
2. extractSeries WROOM Conflict
if (upperMpn.contains("WROOM")) {
if (upperMpn.startsWith("ESP32")) return "ESP32-WROOM";
return "ESP-WROOM";
}
This means ESP32-S3-WROOM-1 returns ESP32-WROOM instead of ESP32-S3.
3. Missing C6/H2 Types
ComponentType enum doesn't include ESP32_C6_SOC or ESP32_H2_SOC.
