mcp_server: Unix socket server for external tool access

Browse source 
Exposes memory/journal tools over ~/.consciousness/mcp.sock via
JSON-RPC 2.0 (MCP protocol). External processes (consciousness-mcp,
poc-memory) will connect here instead of accessing the store directly.

Handles: initialize, tools/list, tools/call
Dispatches to the same tool handlers the agent uses internally.
