DRAFT: DO NOT MERGE Migrate Agentspan docs and examples

[nickorkes]

Summary

• migrate 28 public Agentspan docs pages from Agentspan origin/main into a dedicated Orkes docs section
• place Agentspan under Developer Guides > AI Orchestration and Agentic Workflows
• convert MkDocs markdown to Docusaurus MDX, including admonitions and internal doc links
• keep excluded/internal Agentspan design-doc references as source GitHub links

Source refs

• Agentspan source: agentspan-ai/agentspan@c873e60
• Orkes docs base: 63ca49e

Validation

• migrated page inventory audit passed: 28 expected pages, 28 generated pages, all sidebar IDs present
• migrated link syntax audit passed: no stale /docs links, .md local links, or MkDocs admonitions remain
• npm run build completed successfully
• smoke checked generated output for Agentspan overview, Support Triage example, CLI reference, and AI Orchestration sidebar card

Notes: Docusaurus build still reports existing broken-link/broken-anchor warnings outside the new Agentspan section.
