MaIN.NET.0.10.12

0.10.10 release

• Adds WithMaxIterations() to ToolsConfigurationBuilder and McpContext to override the default tool-call iteration limit.
• Fix: MCP loop now sends a final synthesis request instead of returning an error string when the iteration cap is reached.
• Fix: Gemini/Vertex backends now throw NotSupportedException when WithMaxIterations is used instead of silently ignoring the value.
