OneCAD-Draft/src/ui/window/alias_editor.rs

//! Command-alias editor — an in-canvas modal (Plan B) for adding, remapping and
//! removing command-line aliases (the `ocad.pgp` table). Opened by ALIASEDIT.
//! Rows are `(alias, command)`; edits are buffered in `alias_editor_rows` and
//! committed to the alias table when the dialog closes. Mirrors the editable-row
//! pattern of the attribute editor and plugin manager.
