* feat: add portable ESP32 development skill Add source-backed workflows, safe templates, native CLI routing, and a read-only preflight for ESP32 hardware and firmware work.\n\nAI assistance: research, drafting, implementation, and review used OpenAI Codex and delegated DeepSeek agents under human direction. * docs: harden ESP32 family and security guidance Add source-backed family traps, brownout, calibration, USB recovery, and security-mode boundaries found during independent review.\n\nAI assistance: independent audits and drafting used delegated DeepSeek agents and OpenAI Codex under human direction.
