feat: MCP server — bridge Claude Code ↔ EVA 42 tools via stdio JSON-RPC

- Add POST /api/v1/tools/execute REST endpoint (secured by MCP_API_KEY)
- Create cmd/mcp-server/main.go — full MCP stdio server with 42 tools:
  Memory (5), Communication (7), Productivity (5), Media (4),
  Database (4), Code/Skills (5), Filesystem (3), Smart Home (2),
  Webhooks (3), Self-Coding (4), Multi-LLM (1)
- Add .mcp.json for Claude Code project-level MCP registration
- Maps MCP tool names (eva_*) to EVA internal tool names
- All calls routed through EVA API HTTP bridge
