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.

+//! Coverage test generator for mingling.
+//!
+//! This script requires the **fork** of cargo-llvm-cov:
+//! <https://github.com/Weicao-CatilGrass/cargo-llvm-cov>
+//!
+//! The upstream `report` command cannot include binaries of non-workspace
+//! crates (examples and test crates) and unconditionally filters
+//! `tests`/`examples` source files. The fork adds two flags to fix this:
+//!
+//! - `--object <PATH>`: include arbitrary binaries in the report
+//! (upstream issue taiki-e/cargo-llvm-cov#367)
+//! - `--include-examples`: stop filtering source files under the
+//! `examples` directory (upstream issue taiki-e/cargo-llvm-cov#503)
+//!
+//! The script itself does not use `--include-examples`; it passes
+//! `--no-default-ignore-filename-regex` and supplies its own filter so that
+//! `tests`/`benches` directories stay in the report too.
+//!
+//! Install it with:
+//!
+//! ```bash
+//! cargo install --git https://github.com/Weicao-CatilGrass/cargo-llvm-cov cargo-llvm-cov
+//! ```
