refactor(aspire): flatten skill to references/, version-gate MCP tools, simplify integrations catalog

- Move all reference docs from cli/, mcp/, framework/ subfolders into references/ per agentskills.io spec

- Update all cross-references in SKILL.md and reference files

- Version-gate MCP tools: 9 tools in 13.1+, docs tools (list_docs/search_docs/get_doc) in 13.2+

- Simplify integrations-catalog.md to lead with MCP tool discovery (list_integrations/get_integration_docs)

- Remove .vscode/mcp.json (test artifact from aspire mcp init)
