feat: separate ses-test CLI install via subdirectory

Add cli/pyproject.toml so analysts can install only ses-test
without the monitoring daemon or Zabbix integration.

pip install "ses-test @ git+https://...#subdirectory=cli"
→ only ses-test binary, no ses-monitor in PATH

Root pyproject.toml unchanged — daemon install still provides both.

docs: rename section to 'Установка ses-test'

cli/pyproject.toml
