chore: reorganize dev tools into dev/ directory and consolidate configsHEADmain

Move CI, dev tools, and configs from root-level scattered locations into
a
unified `dev/` directory structure. Update all references across build
scripts, documentation, and editor configurations.

Also consolidate editor config generation into build.rs for automated
synchronization of rust-analyzer settings across VS Code and Zed.

     CI workflow and local execution guide for Mingling

Translated text may differ; the structure may not.
