* Add ESP32 Power Management lessons learned document
Documents our experimentation with ESP-IDF DFS and why it doesn't
work well for Meshtastic (RTOS locks, BLE locks, USB issues).
Proposes simpler alternative: manual setCpuFrequencyMhz() control
with explicit triggers for when to go fast vs slow.
* docs(prompts): fix markdown fence language tags
* docs: remove ESP32 power management notes
