SpacehuhnTech/nightly-deauther ? reverse-engineered prompt

Build me a simple GitHub repo that automatically creates nightly ESP8266 Deauther firmware builds and publishes the .bin files as release downloads.

I want it to make two downloadable builds, one for Deauther V2 and one for Deauther V3, both for an ESP8266 with 1MB flash. The workflow should run after every push, compile the firmware, and overwrite the latest nightly release so the download links always point to the newest build. Make the README clear and practical, with the exact flash command someone can copy and use with esptool after downloading the binary.

Keep it focused on the build and release automation, not on a full app. If you need to check current GitHub Actions or ESP8266 build docs online, go ahead and look them up.
