Background

Nacos does not ship the SkillSpector runtime by default, while the skill-spector pipeline needs a local runtime command for Nacos 3.3.0+ setups.

Expected behavior

nacos-setup should be able to install the SkillSpector runtime and configure Nacos to use it when the selected Nacos version supports the plugin.

Scope

• Add a nacos-setup skill-spector install command with online and offline runtime package sources.
• Install runtime files under the existing ~/ai-infra/ai-pipeline/skill-spector/<version> runtime layout.
• Configure skill-spector plugin properties only for Nacos 3.3.0+.
• Keep skill-scanner and skill-spector configuration additive when both are present.
• Cover the installer and package contents with tests.

Validation

• bash tests/test_syntax.sh
• bash tests/test_package.sh
• bash tests/test_skill_spector_runtime_install.sh
• bash tests/test_skill_scanner_config.sh
• bash tests/test_skill_scanner_preservation.sh
