[BUG] Resuming sessions doesn't work in non-interactive mode (Claude Code SDK)

I'm running in MacOS and run the following commands:

$ claude -p --session-id 0f096bd6-56cd-4fc4-aaa2-331954a6d83e "hello"
Hello! I'm Claude Code, ready to help you with software engineering tasks. What would you like me to work on?

$ claude -p --resume 0f096bd6-56cd-4fc4-aaa2-331954a6d83e "what is 2+2"
4

$ claude -p --resume 0f096bd6-56cd-4fc4-aaa2-331954a6d83e "what did i jsut ask"
You asked "hello" - which was a greeting.

Notice how claude is not aware of my previous conversations in this session. It seems that --resume doesn't work at all in non-interactive mode.

This prevents a lot of potential SDK integrations from being built.
