Teknium 04baab5422 fix(mcp): combine content and structuredContent when both present (#7118) ...

When an MCP server returns both content (model-oriented text) and
structuredContent (machine-oriented JSON), the client now combines
them instead of discarding content.  The text content becomes the
primary result (what the agent reads), and structuredContent is
included as supplementary metadata.

Previously, structuredContent took full precedence — causing data
loss for servers like Desktop Commander that put the actual file
text in content and metadata in structuredContent.

MCP spec guidance: for conversational/agent UX, prefer content.
