♻️🍱 config, cli, vanth, vanth_derive, varo: Reformatted code and added editor configuration files

- Added `.zed/settings.json` to configure rust-analyzer with `leptosfmt`.
- Created `rustfmt.toml` with max width 120 and comment wrapping settings.
- Applied consistent formatting across all modified crates using rustfmt.
- Reorganized import statements and improved code style in multiple modules.
