Function emit_claude_code_with_context 

pub fn emit_claude_code_with_context(
    ir: &WarbleIr,
    out_dir: &Path,
    target_id: &str,

    models: &ModelConfig,

) -> Result<(), DispatchError>

As emit_claude_code_with_realization, with an explicit host-normalized context payload. This is the seam a host uses to supply that payload itself; the dispatcher performs no project I/O of its own, and no CLI flag selects what the payload contains.
