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

# Games
Tachi supports multiple games at the same time. It does
this using Games and Playtypes.
*****
## What's a playtype?
A playtype is a 'sub game' for a given game. For example,
DDR has two 'playtypes', one where the player plays on 4
panels, and one where the player plays on 8 panels.
For DDR, these are referred to as SP and DP - corresponding
to Single Play and Double Play.
Games **MUST** have playtypes, even if the game only has
one practical playtype!
For this scenario, the playtype `Single` is used, so for
something like SDVX, it would be SDVX Single.
### Why?
Playtypes are for separating different scores on the same
game, we don't want to get a user's DP scores mixed with
their SP scores as, for all intents and purposes, they are
completely separate games that need completely different
skills!
As for why games **MUST** have playtypes, it's generally
for futureproofing, and it works nicely with the codebase.
For games that don't *really* have multiple playtypes, this
fact is hidden in the UI, but might still poke up in URLs.
## What games and playtypes are supported?
### Kamaitachi
The following games are supported on [Kamaitachi](https://kamai.tachi.ac).
| Name | Internal Name | Playtypes |
| :: | :: | :: |
| beatmania IIDX | `iidx` | `SP`, `DP` |
| CHUNITHM | `chunithm` | `Single` |
| MÚSECA | `museca` | `Single` |
| SOUND VOLTEX | `sdvx` | `Single` |
| WACCA | `wacca` | `Single` |
| pop'n music | `popn` | `9B`[^1] |
| jubeat | `jubeat` | `Single` |
| GITADORA | `gitadora` | `Gita`, `Dora` |
| maimai DX | `maimaidx` | `Single` |
| maimai | `maimai` | `Single` |
| O.N.G.E.K.I. | `ongeki` | `Single` |
| Dance Dance Revolution | `ddr` | `SP`, `DP` |
### Bokutachi
The following games are supported on [Bokutachi](https://boku.tachi.ac).
| Name | Internal Name | Playtypes |
| :: | :: | :: |
| BMS | `bms` | `7K`, `14K` |
| unnamed_sdvx_clone | `usc` | `Controller` `Keyboard`[^2] |
| PMS | `pms` | `Controller`, `Keyboard`[^2] |
[^1]: Pop'n *had* some other playtypes, namely a 5-Button mode, but it seems to be removed now. 9B is used instead of single here for futureproofing.
[^2]: This use of playtypes is a small hack to make separate leaderboards for keyboard and controller players. The split is necessary because the two input mechanisms are *very* different at high levels, but there are still a lot of keyboard players. It's a compromise!
