}

Host capabilities exposed to Lua stdlib.

Every field is optional. Missing file, process, and dynamic-loading hooks produce Lua errors or Lua failure tuples. On bare wasm32-unknown-unknown, missing stdio/time/env/temp hooks avoid unsupported Rust std stubs and fail at the Lua boundary. Native builds may still use compatibility fallbacks for some stdio and OS functions when hooks are absent.
