Function render_public_script_error 

pub fn render_public_script_error(
    error: &WritePlaneError,
    statement_index: usize,
    partial_results: Vec<Value>,
) -> (u16, Value)

Render one script (execute-multiple) failure: the same classification ladder as render_public_sql_error with the script’s statement_index + partial_results keys, preserving the completed prefix of the ordered autocommit script (the replicator’s old script_sql_error, arm for arm).
