[Feature Request] Add customizable syntax highlighting theme colors for terminal output

Bug Description
Please allow people to customize syntax highlighting, and otherwise fully customize all terminal colors so things match, looking forward to it, thank you 👍

https://code.claude.com/docs/en/terminal-config

(you cannot customize the diff or code syntax highlighting, why are those themes hardcoded into the project 🤔, seems like an easy quick fix/win).

Note too: everything ideally should be customizable, including the little character color when you first open claude, all the little things. Would make the whole dev/terminal ux really nice and polished, thanks.
