ESP Radio Runtime

Final owner for ESP radio/protocol adapter code that is platform-bound but not an app shell responsibility.

Current migrated source:

• meshtastic_radio_adapter.h
• meshtastic_radio_adapter.cpp

Evidence:

• migrated from the removed historical ESP-IDF app implementation root
• active source ownership now lives under final platform ownership

Rules:

• do not select UX packs here
• do not own app shell startup or loop sequencing here
• do not include removed legacy app implementation roots
• keep protocol behavior unchanged unless a protocol-specific change is made
