chore(catalog): refresh 2026-10-04

- multica/install.sh (Linux/macOS/WSL): downloads the fork-built multica
  CLI (0.6.1-arka, agent-arka runtime support) from arka/public releases,
  verifies SHA256, installs to /usr/local/bin or ~/.local/bin, PATH.
- multica/install.ps1 (Windows): same, installs to ~/.multica/bin.
- multica/README.md + root README table entry.
- Release multica-v0.6.1-arka hosts multica-cli-* tarballs/zip + checksums.

+# Multica fork CLI (Arka)
+
+Кастомный билд CLI Multica от Arka: поддержка **agent-arka** runtime (провайдер
+`agent-arka` на `plan.arka-ai.ru`), Arka SSO, русская локализация. Скачивается
+из публичных релизов этого репозитория; токен не нужен.
+
+## Установка
+
+macOS / Linux / WSL:
+
+```bash
+curl -fsSL https://git.arka-ai.ru/arka/public/raw/branch/main/multica/install.sh | bash
+```
+
+Windows (PowerShell):
+
+```powershell
+irm https://git.arka-ai.ru/arka/public/raw/branch/main/multica/install.ps1 | iex
+```
+
+Бинарь ставится в `/usr/local/bin` (или `~/.local/bin`), на Windows — в
+`~\.multica\bin`, и добавляется в `PATH`.
+
+## Подключение к серверу
+
+```bash
+multica setup self-host \
+  --server-url https://plan.arka-ai.ru \
+  --app-url https://plan.arka-ai.ru
+```
+
+Команда настроит CLI, откроет браузер для входа и запустит daemon.
+
+## Проверка
+
+```bash
+multica version            # 0.6.1-arka
+multica daemon status      # running; агенты включают agent-arka
+```
+
+Проверить, что бинарь умеет agent-arka:
+
+```bash
+multica daemon probe-runtimes
+# provider_summary должен содержать "agent-arka"
+```
+
+## Пин версии
+
+```bash
+MULTICA_VERSION=0.6.1-arka curl -fsSL .../multica/install.sh | bash
+```
+
+## Релизы
+
+Бинари публикуются в [релизах](https://git.arka-ai.ru/arka/public/releases/tag/multica-v0.6.1-arka):
+`multica-cli-<version>-linux-{amd64,arm64}.tar.gz`,
+`multica-cli-<version>-darwin-{amd64,arm64}.tar.gz`,
+`multica-cli-<version>-windows-amd64.zip`, `checksums.txt`.
