Sessions with a custom system prompt now automatically omit git status from prompt context
What
When a session is started with a custom system prompt (typically an SDK or other non-interactive use of Claude Code), it now automatically sets omitGitStatus: true, which leaves out the current git status from the context given to the model.
Why
Git status is normally included to give Claude awareness of uncommitted changes, but a custom system prompt usually means the caller is building a specialized setup where that default context may not be wanted or relevant, so it's now skipped automatically in that case.
