bug: MCP server to aded to q-cli

Checks

• I have searched github.com/aws/amazon-q-developer-cli/issues and there are no duplicates of my issue
• I have run q doctor in the affected terminal session
• I have run q restart and replicated the issue again

Operating system

macos

Expected behaviour

mcp server available in /tools list

Actual behaviour

mcp.json is added to .amazonq/mcp.json according to https://github.com/awslabs/mcp/blob/main/src/aws-documentation-mcp-server/README.md

but q-cli does not see this config and is not adding to tools

> /tools

Current tool permissions:
- execute_bash    Write-only commands [Default]
- report_issue    Trusted [Default]
- use_aws         Write-only commands [Default]
- fs_write        Per-request [Default]
- fs_read         Trusted [Default]

there should appear:

- awslabs.aws-documentation-mcp-server ___read_documentation
- awslabs.aws-documentation-mcp-server ___search_documentation

to be able use aws mcp when prompting

El issue identifica .amazonq/mcp.json y el comando /tools; empieza reproduciendo el problema con q doctor y q restart en macOS 12.5.1 usando q 1.7.3, y después sigue el recorrido hasta encontrar dónde la CLI carga la configuración de MCP y rellena /tools. Se considera completado cuando las dos herramientas MCP de aws-documentation aparecen en la lista de /tools.
