Detailed Description

Compatibility include wrapper for ESP-IDF headers when building with -Wpedantic in C++.

ESP-IDF is primarily a C codebase and some of its public headers legitimately use C extensions such as:

• zero-length arrays (uint8_t payload[0])
• flexible array members (uint8_t ssi[])

When those headers are included from C++ translation units with -Wpedantic, GCC emits warnings like:

• "ISO C++ forbids zero-size array"
• "ISO C++ forbids flexible array member"

Those warnings are not actionable from the application side without patching ESP-IDF. This wrapper locally suppresses -Wpedantic while including the affected headers, allowing us to keep -Wpedantic enabled for our code.
