refactor(claude): settings.json отдан Claude Code, базовые настройки в settings.local.json

- Зачем:
  - Claude Code перезаписывает settings.json при каждом «always allow», что создавало
    конфликт с managed-копией из dotfiles при повторном запуске install.sh.
- Что:
  - settings.json удалён из репозитория, Claude Code владеет им полностью.
  - создан settings.local.json (базовые permissions + statusLine), деплоится через симлинк.
  - install.sh: копирование + шаблон заменены на ln -sf с бэкапом и guard для edge cases.
  - check.sh: проверка обновлена под симлинк вместо «файл + chmod 444».
  - тесты: старый тест копирования заменён на 4 новых (симлинк, бэкап, директория, stow-миграция).
- Проверка:
  - bash tests/test_install.sh (15 тестов).
  - bash agents/.agents/skills/dotfiles-check/check.sh.
