fix(deps): bump cogito to fix MCP image-content panic (#10101)

Bumps github.com/mudler/cogito from
  v0.9.5-0.20260315222927-63abdec7189b
to
  v0.9.5-0.20260531081147-2c13b6ac29cf

The new revision contains mudler/cogito#50 which replaces the hard
*mcp.TextContent type assertion in mcpTool.Execute with a type switch.
Any MCP tool that returns image, audio, resource-link, or
embedded-resource content previously caused:

  panic: interface conversion: mcp.Content is *mcp.ImageContent, not *mcp.TextContent

bringing down the entire host process.  The new code summarises
non-text blocks with a descriptive marker so the model receives
something useful without crashing.

Closes #10101
