fix(ai): try overriding timeout to disable error

The Anthropic SDK preemptively throws an error if it thinks a response
is going to take longer than 10 minutes:
https://github.com/anthropics/anthropic-sdk-typescript#long-requests

According to this documentation, overriding the `timeout` option
disables this error. In this commit the option is changed to the default
value of 10 minutes plus an additional 1 second; it is assumed based on
the documentation's phrasing that it is not necessary to make the
timeout higher but simply to specify a value.
