feat(mcp):added MCP server (#97)

* docs(specs): design research-agent MCP tools and ktx mcp daemon

Adds the 2026-05-14 design spec for exposing four new MCP tools
(discover_data, entity_details, dictionary_search, sql_execution),
shipping a ktx-research skill, and introducing an HTTP-only ktx mcp
daemon so external agents can use KTX as a research-capable context
layer.
