I2C Monitor TUI Tool

This is an I2C Monitor TUI for the TotalPhase Beagle I2C/SPI bus analyzer. The
default UI is a heavy GUI, this leverages the Beagle API library for Python
to create a lightweight TUI usable over SSH.

Features:
- Display traffic as raw, SMBus packets, MCTP messages, or SPDM commands.
- Buffer scrollback, command history
- Ability to change how the data buffer is viewed (move between raw and SPDM, for example)
- Ability to save the buffer as processed text or raw I2C traffic.
- Ability to attach to any Beagle device plugged into the system.
- Ability to reconfigure beagle settings on the fly.

This utility has been generated entirely via Claude Code (Sonnet 4)
