Pull request overview

Implements a new nested skills command group (“SkillOps”) in scripts/agent_context.py to inventory/validate repository-local Agent Skills under .agents/skills/, generate deterministic registry and health reports, sync compact skill routes into .agents/routing.md, and scaffold eval workspaces / run explicit Codex evals. This is integrated into top-level check() and documented across READMEs, extension guides, and the changelog, with expanded unit test coverage.

Changes:

• Add SkillOps core implementation: skill discovery, dependency-free frontmatter parsing, local reference + eval manifest validation, registry/report generation, routes sync, and eval workspace/runner helpers.
• Integrate skill validation and route checking into the existing check() flow and add CLI subcommands under skills.
• Update documentation and add extensive tests covering success and failure cases (including symlink and unsafe-path handling).
