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.

* Refine research-agent MCP tools spec after adversarial review iteration 1

* Refine research-agent MCP tools spec after adversarial review iteration 2

* Refine research-agent MCP tools spec after adversarial review iteration 3

* Refine spec: drop connectionName compat carve-out and ground summary/snippet provenance per kind

* feat(context): expose read-only SQL validation port

* feat(context): register MCP sql execution tool

* feat(context): execute MCP SQL through validated connector path

* test(context): update SQL analysis port fixtures

* docs: add research-agent MCP sql execution foundation plan

* feat(context): add scan-backed entity details service

* feat(context): register MCP entity details tool

* docs: add research-agent MCP dictionary_search plan

* feat: add MCP discover data service

* feat: expose discover data MCP tool

* feat: wire local discover data MCP port

* feat(cli): install KTX research skill

* feat(cli): configure MCP clients in setup agents

* feat(cli): support Claude local MCP setup scope

* docs: add research-agent MCP setup-agents plan
