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.

Pass `--show-diff` to `git-unlock` and restructure CI steps as
(command, args) pairs to support per-step arguments. The diff prints
tracked workspace changes before they are discarded.

Convert per-check CI commands into a unified git-lock protected flow and
add a consolidated report job that aggregates all matrix run results
into the job summary.

Add a new CI check that verifies translated docs directories mirror
the English reference structure, comparing structural signatures of
markdown files including headings, code fences, and list types.

Refactor the CI workflow to build distributable packages in
parallel with checks, then upload them to the Pages deployment
alongside documentation. Simplify artifact naming to use only the
OS rather than commit SHA and date, and add SHA-256 checksums.
