zk e363bd2532 docs: migrate from mkdocs to mdbook (#1558)
* docs: migrate from mkdocs to mdbook

- Rename old mkdocs docs/ to old-docs/ for reference
- Set up new docs/ with mdbook (book.toml + src/ tree)
- Mirror full nav structure from mkdocs.yml into SUMMARY.md
- Add Justfile-docs with docs-serve, docs-build, docs-check, docs-install recipes
- Import Justfile-docs from root Justfile
- Rewrite .github/workflows/docs.yml: build step uses taiki-e/install-action
  to install mdbook, split into separate build + deploy jobs, PR builds
  run the check step too

* ci(docs): pin actions to SHAs, install mdbook via release binary

* ci(docs): install mdbook from apt instead of curling a release binary

* dev: replace mkdocs python stack with mdbook in dev image

* ci(docs): apt only works on Debian; restore release binary install for Ubuntu CI

* docs: fix duplicate file entries in SUMMARY.md

* docs: remove docs-install recipe

* docs: remove site-url from book.toml to fix asset loading

* dev: install mdbook from upstream release binary, not Debian apt

The Debian package (0.4.x+ds) strips bundled font assets, leaving the
built site without fonts/fonts.css. Use the upstream tarball (same as CI)
so the theme is complete. Handles x86_64 and aarch64.

* docs: vendor mdbook tarballs in dev/mdbook/, install from there

Dockerfile.dev uses COPY + tar to install the right arch at build time.
CI extracts the x86_64 tarball directly from the checkout.
No network access required for either — and no stripped-fonts Debian package.

* fix: unwritten

OAuth2 Integration

Tachi provides an OAuth2 API and some other things so that you can create your own clients and retrieve user api keys safely.

For a detailed explaination on how to use the OAuth2 flow, you can check Using OAuth2 With Tachi
