Three pieces, all required for an end-to-end MCP tool call:
* McpToolService used generic spec names "request"/"response" instead of
"mcp-tool-request"/"mcp-tool-response", so RequestResponseSpec's
flow-config topic lookup never matched and consumers bound to literal
subjects nobody else publishes to.
* Add entrypoints/mcp-tool.mjs (mirrors agent/librarian entrypoints) so
the service can be launched in the prebuilt trustgraph-ts image.
* Add a `mcp-tool` service block to deploy/docker-compose.yml.
With these three fixes plus a `mcp-tool-request`/`mcp-tool-response`
entry in each flow's topics map, the agent ReAct loop can now invoke
remote MCP tools (verified end-to-end against Brave Search and FireCrawl).

Pipeline fixes:
- Fix agent getting empty response from graph-rag by combining answer +
explain data in single message (RequestResponse returns first msg)
- Fix Doc RAG pipeline: add content field to Qdrant doc payload, seed 10
document chunks, fix type mismatches across base/flow/client
- Forward explainability events from agent's KnowledgeQuery to client
- Add "agent" to TERM_BEARING_RESPONSE_SERVICES for triple translation
- Fix embeddings env var (OLLAMA_URL), user/collection threading, edge
scoring threshold, and various protocol mismatches
Branding:
- Rename TrustGraph → Beep Graph (title, sidebar, settings, about)
- Custom lambda + ThugLife pixel glasses SVG logo component
- Forest green color palette (brand-50 through brand-900)
- SVG favicon + PNG icons (16/32/180/192/512)
- PWA manifest with service worker for offline shell caching
- Splash screen with animated logo pulse on app load
- Ambient glow background with drifting green radial blobs

Add the full MCP tool pipeline enabling agents to invoke external tools
(like Brave Search) via MCP servers:
- Add ToolRequest/ToolResponse types and mcp-tool topics to @trustgraph/base
- Create McpToolService (FlowProcessor) that connects to external MCP servers
via @modelcontextprotocol/sdk StreamableHTTP transport
- Add createMcpTool() to wire MCP tools into the agent's ReAct loop
- Implement config-driven tool registration in AgentService with backward-
compatible fallback to hardcoded tools
- Add tool filtering by group and state (port of Python tool_filter.py)
- Register mcp-tool in gateway dispatcher and export from @trustgraph/flow
- Fix flow restart race condition: skip restart when flow definitions unchanged
- Update seed config with MCP server config and tool definitions
- Add run scripts for MCP tool service and Brave Search MCP server

- Fix FalkorDB triples query: client v5 returns objects not arrays, use named field access
- Fix embeddings service: align spec names to "embeddings-request"/"embeddings-response"
- Fix client triplesQuery: read `triples` field instead of `response` from backend
- Fix graph page crash: guard against non-array triples, accept literals as entity nodes
- Add seed:demo script for AI industry knowledge graph (254 triples, 64 entities)

Store the initialization Promise in the requestors map synchronously
before yielding, so concurrent callers for the same key await the same
instance — prevents orphaned RequestResponse objects and duplicate NATS
subscriptions. Mirrors upstream fix 8f18ba02.
