Remove context7 from scout workflow to fix gateway timeout

[Copilot]

Scout workflow failing due to MCP Gateway hanging indefinitely during context7 server initialization. Gateway successfully launches arxiv but blocks waiting for context7 response, never starts HTTP server, health check times out after 120s.

Changes

• Removed context7 MCP server import from scout workflow
• Updated prompt documentation to remove Context7 from available research tools list
• Recompiled workflow to regenerate lock file without context7 container and configuration

Technical Details

Gateway logs show successful initialization of other servers but hang at:

[2026-01-26T02:32:37Z] [INFO] [backend] Starting MCP server: context7
--- End of mcp-gateway.log ---

No timeout exists for individual MCP server launches. The context7 container starts but never completes MCP protocol handshake, blocking all subsequent initialization.

Follow-up

• mcp-inspector workflow also imports context7 and has similar failures
• Root cause investigation: why context7 hangs, add per-server launch timeout to gateway
