- Support four hardware backends: serial, gpio, zenoh, mock - Serial connector for Arduino/USB microcontrollers - GPIO connector for Raspberry Pi and Jetson (RPi.GPIO / Jetson.GPIO) - Zenoh connector for network-distributed setups - Mock connector as default for safe out-of-box experience - Cooldown parameter to prevent LLM context flooding - All backends degrade gracefully if library not installed - Add pir_guard.json5 config with all required schema fields - Add docs/robotics/pir_hc_sr501.md hardware documentation - Update docs/developing/4_inputs.md with PIR entry

Summary
Adds a new input plugin for the HC-SR501 Passive Infrared (PIR) motion sensor. The plugin converts hardware motion detection events into natural language context for the LLM. #365

mock— safe to run on any machine without hardwarecooldownparameter prevents LLM context flooding when sensor stays HIGH (HC-SR501 can hold HIGH up to ~200s)
