gptel: Change gptel-include-reasoning default
* gptel-request.el (gptel-include-reasoning): Change the default
value of this option to `ignore', meaning that reasoning text in
LLM responses will be included in buffers but ignored on new
conversation turns by gptel-send. (#1326)
* NEWS (Breaking changes): Mention change and reason.
