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` Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
