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.

Add temporary commit and restore commands to stabilize the workspace
during CI runs, with safety checks and error handling.

Add three utility commands to regenerate generated files:
- `docsify-refresh`: fix code-box blank lines and regenerate sidebars
- `example-refresh`: regenerate example docs module and examples index
- `features-refresh`: regenerate the features module from Cargo.toml

suffix

Add a new `test-examples` command that builds each example
and runs its `test.toml` cases, reporting failures and
setting a non-zero exit code when any example fails.

Add `markdown-compare` and `markdown-compare-all` commands to verify
that translated docs maintain the same structure as the reference.
Compare heading levels, code fences, lists, quotes, and other
structural elements while allowing text differences.

Add `markdown-check` and `markdown-check-all` commands to verify Rust
code blocks in markdown files. Code blocks are compiled as test
projects, sharing temporary crates based on dependency configuration for
parallel execution.

Add a new `test-all` command that runs tests across all crates with
optional per-crate command overrides via `mingling-ci.toml` files.
