massive deploy!

Grug is now powered with GPT-5 -- it's slower, but after a lot of system prompt tuning, I'm finding it's ability to plan and write superior than O3. One of my test cases has been making endurance training programs -- try this on a 'prompt' page of your choosing. On finalization of a plan, it will trigger Big Brain to fill out daily blocks.

Big Brain also has faster generation and actually more consistent with Gemini 2.5 flash and 2.5 Pro for task verification.

Lots of improvements on system prompts for all chat llm calls.

Major speed optimization on chat page loading.

Regression fixes on Add Block button.
