Walkthrough

This pull request updates documentation: adds a v3.0.0rc1 release entry to docs/changelog.mdx and docs/updates.mdx; updates version wording and install examples from 3.0.0b2 to 3.0.0rc1 across getting-started and servers docs; registers two new docs.json pages (python-sdk/fastmcp-server-middleware-dereference and python-sdk/fastmcp-server-tasks-notifications). No code, API signatures, or runtime behavior were changed.

⚠️ Potential issue | 🟡 Minor

Make the Azure OBO snippet runnable or replace it with a doc link.

The snippet uses ellipsis and omits setup, so it isn’t copy/paste runnable. Either expand it into a full example (imports + server setup + expected behavior) or replace it with a short link to the dedicated guide.

✏️ Suggested edit

-```python
-from fastmcp.server.auth.providers.azure import EntraOBOToken
-
-@mcp.tool()
-async def get_emails(
-    graph_token: str = EntraOBOToken(["https://graph.microsoft.com/Mail.Read"]),
-):
-    # OBO exchange already happened — just use the token
-    ...
-```
+See the [Azure integration guide](/integrations/azure) for a runnable OBO example.

As per coding guidelines: "Always include complete, runnable code examples that users can copy and execute in MDX documentation".

⚠️ Potential issue | 🟡 Minor

Use descriptive link text for the full changelog.

Raw URLs are harder to scan and less accessible; use a descriptive label.
