Ehu shubham shaw contribution --> Hardware support (#306) 
* feat: add ZeroClaw firmware for ESP32 and Nucleo

* Introduced new firmware for ZeroClaw on ESP32 and Nucleo-F401RE, enabling JSON-over-serial communication for GPIO control.
* Added `zeroclaw-esp32` with support for commands like `gpio_read` and `gpio_write`, along with capabilities reporting.
* Implemented `zeroclaw-nucleo` firmware with similar functionality for STM32, ensuring compatibility with existing ZeroClaw protocols.
* Updated `.gitignore` to include new firmware targets and added necessary dependencies in `Cargo.toml` for both platforms.
* Created README files for both firmware projects detailing setup, build, and usage instructions.

* feat: enhance hardware peripheral support and documentation

- Added `Peripheral` trait implementation in `src/peripherals/` to manage hardware boards (STM32, RPi GPIO).
- Updated `AGENTS.md` to include new extension points for peripherals and their configuration.
- Introduced comprehensive documentation for adding boards and tools, including a quick start guide and supported boards.
- Enhanced `Cargo.toml` to include optional dependencies for PDF extraction and peripheral support.
- Created new datasheets for Arduino Uno, ESP32, and Nucleo-F401RE, detailing pin aliases and GPIO usage.
- Implemented new tools for hardware memory reading and board information retrieval in the agent loop.

This update significantly improves the integration and usability of hardware peripherals within the ZeroClaw framework.

* feat: Introduce hardware auto-discovery and expanded configuration options for agents, hardware, and security.

* chore: update dependencies and improve probe-rs integration

- Updated `Cargo.lock` to remove specific version constraints for several dependencies, including `zerocopy`, `syn`, and `strsim`, allowing for more flexibility in version resolution.
- Upgraded `bincode` and `bitfield` to their latest versions, enhancing serialization and memory management capabilities.
- Updated `Cargo.toml` to reflect the new version of `probe-rs` from `0.24` to `0.30`, improving hardware probing functionality.
- Refactored code in `src/hardware` and `src/tools` to utilize the new `SessionConfig` for session management in `probe-rs`, ensuring better compatibility and performance.
- Cleaned up documentation in `docs/datasheets/nucleo-f401re.md` by removing unnecessary lines.

* fix: apply cargo fmt

* docs: add hardware architecture diagram.

Overview

Arduino Uno is a microcontroller board based on the ATmega328P. It has 14 digital I/O pins (0–13) and 6 analog inputs (A0–A5).

Digital Pins

  • Pins 0–13: Digital I/O. Can be INPUT or OUTPUT.
  • Pin 13: Built-in LED (onboard). Connect LED to GND or use for output.
  • Pins 0–1: Also used for Serial (RX/TX). Avoid if using Serial.

GPIO

  • digitalWrite(pin, HIGH) or digitalWrite(pin, LOW) for output.
  • digitalRead(pin) for input (returns 0 or 1).
  • Pin numbers in ZeroClaw protocol: 0–13.

Serial

  • UART on pins 0 (RX) and 1 (TX).
  • USB via ATmega16U2 or CH340 (clones).
  • Baud rate: 115200 for ZeroClaw firmware.

ZeroClaw Tools

  • gpio_read: Read pin value (0 or 1).
  • gpio_write: Set pin high (1) or low (0).
  • arduino_upload: Agent generates full Arduino sketch code; ZeroClaw compiles and uploads it via arduino-cli. Use for "make a heart", custom patterns — agent writes the code, no manual editing. Pin 13 = built-in LED.
