Bumps fastmcp from 3.2.0 to 3.2.3.

Release notes

Sourced from fastmcp's releases.

v3.2.3: Redis or Not

fakeredis 2.35.0 shipped an undocumented rename (FakeConnectionFakeAsyncRedisConnection) that broke pydocket's memory:// backend, causing fastmcp[tasks] installs to fail at startup with an ImportError. This pins fakeredis<2.35.0 in the tasks extra as a stopgap until a fixed pydocket ships.

v3.2.2: Audience Appreciation

The Azure audience fix in 3.2.1 overcorrected: it switched token validation from client_id to identifier_uri, which fixed custom Application ID URIs but broke the default case where Azure AD v2 tokens set aud to the bare client ID GUID. Both formats are now accepted.

v3.2.1: Audience Participation

Most of the fixes in this patch are about auth providers getting audience validation wrong. Cognito token verification was checking the aud JWT claim, but Cognito access tokens don't include one; they use client_id instead. Azure was hardcoding the raw client ID as the expected audience, ignoring the identifier_uri parameter even though Entra v2.0 tokens use the Application ID URI as aud. Both now validate correctly without changing the provider API. Consent cookies also had an unbounded growth problem in high-DCR-client environments, eventually blowing past reverse proxy header limits; they're now capped as an LRU.

On the OpenAPI side, nullable: true fields from 3.0 specs were leaking into tool input schemas as-is instead of being converted to JSON Schema's type: ["string", "null"]. Server variable templates in base URLs (like https://{region}.api.example.com) were also being passed through raw instead of substituted with their defaults.

Smaller fixes: form submissions from Prefab UI now correctly handle unchecked boolean checkboxes, the client no longer crashes on error responses with empty or non-text content from third-party servers, and asyncio.iscoroutinefunction no longer emits deprecation warnings on Python 3.14.
