M8-M9: README, настройки текстур под платформы, статус проверок

- README: с чего начать, какие команды есть, где что лежит
- TECHNICAL.md: команда headless-сборки с её подводными камнями,
  настройки ASTC под Android/iOS, и честный раздел о том,
  что проверено, а что нет
- PLAN.md: M8 и M9 помечены частичными — визуально игра не запускалась,
  браузер в этом окружении не поднимает главный цикл движка;
  там же список оставшихся хвостов

+# Fool
+
+A mobile card game: *durak*, one player against a bot. Built with
+**Cocos Creator 3.8.8**, targeting Web, Android and iOS, portrait only.
+
+## Getting around
+
+| | |
+|---|---|
+| What the game is | [docs/GAMEPLAY.md](docs/GAMEPLAY.md) — the rules, and the bot's policy |
+| How it is built | [docs/TECHNICAL.md](docs/TECHNICAL.md) — layers, folders, workflows |
+| What is planned | [docs/PLAN.md](docs/PLAN.md) — milestones and their state |
+| Why it is like that | [docs/DECISIONS.md](docs/DECISIONS.md) — choices the specs left open |
+| Driving the editor | [docs/CODE_MODE_SETUP.md](docs/CODE_MODE_SETUP.md) |
+
+## Working on it
+
+```bash
+npm install
+npm test                  # the rules, the bot and the save format, headless
+npm run typecheck         # strict tsc over core/, modules/ and the tests
+npm run check:core-purity # fails if the game logic reaches for the engine
+npm run build:art         # regenerate every sprite from source
+npm run stats:bot         # BasicBot self-play distribution — a tool, not a test
+```
+
+`npm test` needs no editor and no device. That is deliberate: the rules live in a
+pure TypeScript core with no `cc` import, driven as a deterministic state
+machine, so the entire rule set is verifiable in a couple of seconds. The soak
+specs play several thousand complete matches and re-check every state invariant
+after every single action.
+
+To see it, open the project in Cocos Creator and press Preview, or build and
+serve it — see *Builds* in [docs/TECHNICAL.md](docs/TECHNICAL.md).

-Mobile: ASTC textures per [ART.md](ART.md), PNG for web.
+### Per-platform texture settings
+
+[ART.md](ART.md) asks for ASTC on mobile and PNG on the web. Compression is set
+per image (or per folder) in the Inspector's texture-compress section, not in
+code, so it has to be applied once in the editor and is then stored in the
+`.meta` files:
+
+| Target | Setting |
+|---|---|
+| `web-mobile` | PNG, as now |
+| `android` | ASTC 6×6 for the card atlas, ASTC 4×4 for the UI sprites |
+| `ios` | the same ASTC settings; the format is supported on every device the game targets |
+
+The card atlas is the only texture where this matters — 2048×2048 uncompressed
+is 16 MB of video memory, and ASTC 6×6 brings that to roughly 1.2 MB. Do it
+before the first device build.
