3//! Wire method: `localPty:resize`.
4//! Forwards a resize event to the PTY master (SIGWINCH) via
5//! `TerminalProvider::ResizeTerminal`. Accepts either positional
6//! `[id, cols, rows]` or object `{ id, cols, rows }` from the workbench.
7//!
8//! Clamps cols/rows to ≥ 1 - portable-pty crashes the IO thread with
9//! "size out of range" on 0×0, which the workbench can emit during
10//! pane drag-storms before the requestAnimationFrame settle.
