feat: Expand microsoft-docs skill with Agent Framework, DevUI, and Semantic Kernel coverage

Major improvements to the microsoft-docs skill:

- Add Microsoft Agent Framework section with two Context7 sources:
  /websites/learn_microsoft_en-us_agent-framework (tutorials, 2282 snippets)
  /microsoft/agent-framework (GitHub repo API detail, 1177 snippets)

- Add comprehensive DevUI workflow reference covering installation,
  programmatic launch, directory discovery, tracing, OpenAI-compatible
  API, OpenAI proxy, authentication, UI modes, .NET integration, and
  external observability export

- Add Semantic Kernel section with three quality-ranked sources covering
  Learn docs, agent framework subset, and GitHub repo

- Add guidance on when GitHub repo sources beat published docs (DevUI
  API reference, .NET integration, extension samples)

- Expand decision table with agent framework scenarios
- Add agent framework query examples for DevUI, SK, and workflows
- Highlight microsoft_code_sample_search with language filter for
  working code snippets

Tested all sources against identical queries to verify quality rankings.
