Add a customizable file reader callback to ChaiScript_Basic, following the same pattern as set_print_handler. When set, the callback is invoked instead of the default filesystem read, enabling use cases like encrypted files, in-memory virtual filesystems, or platform-specific file access (e.g., Android assets). The callback is settable from both C++ and ChaiScript. Co-authored-by: leftibot <leftibot@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
