Return the prompt hash in upload responses (#44325)

## What changed

Add nullable `promptHash` to the upload response, populated from the uploaded `prompt_hash` tag. It identifies the whitespace-normalized SHA-256 of the session base instructions, excludes later developer messages, and is `null` when the reported rollout has no prompt metadata.

Update the protocol schemas, precomputed exports, and generated TypeScript and Python types.
