chore(deps): bump fastmcp to ^3.0.0 and authlib to 1.7.2

sdk/CHANGELOG.md

 ## [Unreleased]
 
+### Changed
+- Bump `fastmcp` from `^2.14.0` to `^3.0.0` (resolves to 3.4.0), which pulls in `authlib` 1.7.2. The MCP adapter now uses `Tool.to_mcp_tool()` to read tool schemas, since fastmcp 3.x `list_tools()` returns `FunctionTool` objects that expose schemas via `parameters`/`output_schema` instead of `inputSchema`/`outputSchema`.
+
 ### Added
 - **Distributed tracing via OpenTelemetry**: Agents now propagate a shared `trace_id` across every message hop. Opt-in via `setup_tracing()`; zero-cost when not configured.
