Opensourcing the SDK code

Hey fellow maintainers !

I was wondering if there is a reason the wrapper code around the Claude Code CLI is not open source. Since this part is only orchestration logic and does not contain any secret sauce or IP, keeping it closed creates a bit of friction for adoption without really adding protection.

Open sourcing this wrapper would help in a few ways:
• It builds trust with developers who want to inspect how the binary is being called.
• It allows the community to fix edge cases and contribute improvements (like [here](https://github.com/anthropics/claude-agent-sdk-typescript/issues/45)) rather than waiting on internal updates.
• It encourages ecosystem growth, since people can create integrations, plugins, and tooling more confidently.
• It aligns with common practice across developer platforms, where binaries are closed but the CLI/SDK layer is transparent.

The goal is simply to make it easier for the community to understand and extend the tool. If there are concerns, I would be happy to discuss them or help structure a minimal open source repo.

Thanks for considering. I really think this would help adoption and developer trust :-)
