docs(skill): синхронизация README, фикс рекомендации Codex sandbox

- Зачем:
  - README отстал от SKILL.md после двух раундов self-review — формы инвокации, /agent, disallowedTools описаны неверно.
  - Рекомендация Codex sandbox_mode = "read-only" была ошибочной: она запрещает не только запись, но и exec — ревьюер не сможет запускать тесты, линтеры, git, MCP-запросы (а это основа верификации находок).
- Что:
  - README и SKILL.md: блок «Tool restrictions» переписан — briefing-only по умолчанию на обоих хостах; жёсткая sandbox упомянута как опция с явным trade-off (на Codex теряется exec).
  - README: Usage block обновлён — добавлены code-vs-plan и code-vs-plan <plan-path>, явное правило bare <file-path> → plan, xhigh как ортогональный effort flag.
  - README: новая короткая секция Language (ответы ревьюера на языке оператора, без флага).
  - README: bullet про structural-only паузы оператора в «What the lead does».
  - README: /agent в Codex section переформулирован как CLI оператора, а не tool лида.
- Проверка:
  - git diff main..HEAD -- README.md SKILL.md
  - Прочитать README целиком и убедиться, что нет противоречий с SKILL.md.

+  built-in `general-purpose` agent has no invocation-time
+  tool-restriction knob, so this path requires the custom definition.
+- **Codex:** `sandbox_mode = "read-only"` applies natively, but it also
+  disables shell exec for the subagent — the reviewer will not be able
