ergomechstore/sofle-v2-zmk ? reverse-engineered prompt

Build me a complete ZMK firmware setup for the Sofle V2 wireless split keyboard so I can flash both halves and use the default keymap right away.

I want the repo to let me build firmware for the left side, right side, and a reset image, then download the flashed files from GitHub Actions. Keep the default layout easy to understand, and include a simple visual keymap image so I can see what each layer does. Also make sure the instructions explain how to put each half into bootloader mode, when to flash one side at a time, and what to do if I need to reset everything first.

It would be great if the keymap is easy to edit later with the online keymap editor or by changing the keymap files directly. If anything about the ZMK docs or current flashing process matters, look it up online and make sure the setup still matches how people actually use it.
