Pull request overview

Adds an ESP-IDF component that integrates CANopenNode with the ESP32 TWAI driver and provides initial target/driver scaffolding.

Changes:

• Introduces ESP32 target definitions (CO_driver_target.h) and a TWAI-backed CANopenNode driver (CO_driver_esp32.c)
• Adds component metadata/build configuration (idf_component.yml, CMakeLists.txt) and initial documentation/license
• Adds CANopenNode as a git submodule

Pull request overview

This PR introduces a new canopennode ESP-IDF extra component which integrates the upstream CANopenNode stack (via submodule) with the ESP TWAI driver, and adds a minimal heartbeat example plus component metadata/CI wiring needed for publishing.

Changes:

• Added an ESP-IDF/TWAI-specific CANopenNode driver target header and ESP32 driver implementation.
• Added a heartbeat example project (generated OD files + app) and basic component scaffolding (LICENSE/README/Kconfig/SBOM/manifest).
• Registered the new component in repo automation/configuration (submodule + upload workflow + issue template component list).
