Add worked examples for multi-server composition and progressive disclosure use cases

[olaservo]

Background

Use Cases 3 (Multi-Server Composition) and 4 (Progressive Disclosure) are two of the most discussed scenarios in this IG, but the documentation currently lacks concrete, worked examples. Contributors and newcomers need detailed scenarios to understand the problems and evaluate approaches.

Scope

Multi-Server Composition (UC #3)

Add a worked example showing:

• A skill that orchestrates tools from 2-3 different MCP servers (e.g., "Research and summarize" using a web-search server + a note-taking server + a file-system server)
• The skill's SKILL.md content with tool references
• How dependency declaration would work (referencing OQ Add Rado's GitHub handle to Facilitators table #4)
• What happens when one required server is unavailable

Progressive Disclosure (UC #4)

Add a worked example showing:

• A complex skill broken into linked files (overview -> detailed steps -> reference)
• The resource listing showing the skill hierarchy
• The loading sequence: agent reads overview, requests detailed steps on demand
• Context management: how much context is consumed at each stage

Version-Adaptive Content (UC #8)

Add a worked example showing:

• A skill that detects framework version and returns appropriate guidance
• Implementation sketch using resource templates: skill:///airflow-guide?version={detected_version}

Acceptance Criteria

• At least 2 worked examples (one for UC Set up the rest of the starting docs #3, one for UC Add Rado's GitHub handle to Facilitators table #4)
• Each example includes: scenario description, SKILL.md content (or equivalent), expected agent behavior, and the MCP resource/tool interactions
• Examples reference real or realistic MCP servers
• Added to docs/use-cases.md under the relevant sections

Note: The worked examples produced by this issue should be usable as test cases in the evaluation matrix (#47). When designing examples, consider structuring them so they can validate specific requirements from #46 across different approaches.
