/boost, ultracode and other magic incancations

ultracode is different to ultrathink (because of course it is...)

ultrathink was "throw more tokens" (it was a Claude feature that has gone away[1])

ultracode is "throw more tokens AND write code that creates and orchastrates subagents": https://code.claude.com/docs/en/workflows

[1] https://claudelog.com/faqs/what-is-ultrathink/ claims it has returned, but that might not be accurate
