    Copies SKILL.md from this package to .agents/skills/structid/ in the consuming repo root.

    Falls back to SolutionDir if the git root cannot be determined.
    Falls back to the directory containing the nearest AGENTS.md file found above the project file.
    Silently skips if the base directory cannot be determined.
    Opt-out: set <StructIdSkill>false</StructIdSkill> in your project or Directory.Build.props.
