grabowski e7a23a3c7e Add LVSolarBuck64 firmware and debug console with uv support 
STM32G474RB firmware for solar buck converter with MPPT, CC control,
Vfly compensation, and adaptive deadtime. Includes Textual TUI debug
console for real-time telemetry, parameter tuning, and SQLite logging.

Added pyproject.toml for uv: `cd code64 && uv run debug-console`
