I'm not sure I understand the objective of this PR. Beast Mode was designed for GPT-4.1 (which is the reason for 4.1 in the name) but this changes that to a lower version (a not a GPT model) and removes the model, while then adding a bunch of specific tools.

The net-new aspect looks to be the memory component, which might be better achieved as just an instructions file rather than in the chat mode.

The author regularly provides updates to this chatmode(https://gist.github.com/burkeholland/88af0249c4b6aff3820bf37898c8bacf). The 3.1 refers to the chatmode version, not the model version. For some reason he did not include the model in his latest version, I have added it back.

@burkeholland can you have a look at this PR to ensure that the right mode is being updated? I'm a little confused at the various beast modes in your gist and which maps to which here.
