This pull request introduces comprehensive documentation improvements and workflow updates to support the new "AI Library Skills" feature for DKNet RESTful API development. The changes include new specification and planning documents, a reusable skill file template, a data model schema, and a checklist to ensure documentation quality and compliance. Additionally, project guidelines are modernized, and minor updates are made to development tooling and CI workflow triggers.

Key highlights:

• Introduces a standardized approach for documenting DKNet library usage as "skill files" to improve AI agent context and developer guidance.
• Provides templates, validation rules, and checklists to ensure high-quality, consistent documentation.
• Updates project guidelines to reflect current architecture, build, and testing practices.
• Includes minor improvements to VS Code recommendations and workflow dispatch triggers.

---

AI Library Skills Documentation Framework

• Added a reusable skill file template (skill-file-template.md) for documenting each DKNet library, specifying required sections, usage patterns, anti-patterns, and test examples.
• Defined a data model schema (data-model.md) for skill files, master index, and composition patterns, including validation rules for compliance.
• Created a requirements checklist (requirements.md) to validate the completeness and quality of each skill file before planning and implementation.
• Added a detailed implementation plan (plan.md) outlining deliverables, constitution checks, and project structure for the AI Library Skills documentation feature.

Project Guidelines and Developer Experience

• Rewrote .github/copilot-instructions.md as "Project Guidelines" to clarify context loading, architecture, build/test conventions, code style, and common pitfalls for contributors and AI agents.
• Updated VS Code extension recommendations, removing obsolete extensions and adding jetbrains.resharper-code for improved code quality tooling.

CI/CD and Workflow Enhancements

• Enabled manual workflow dispatch for the dotnet-publish.yml GitHub Actions workflow to allow on-demand builds.

These updates lay the foundation for consistent, high-quality documentation and improved AI agent support in the DKNet project.
