Support partial shortcut overrides in ShortcutPlugin

[Vi Nguyen (vinguyen12)]

Adds partial override support to ShortcutPlugin, allowing consumers to customize selected built-in shortcut keys without replacing the complete command list.

new ShortcutPlugin({
    shortcutOverrides: {
        bold: {
            modifierKey: 'ctrl',
            shiftKey: false,
            which: 78,
        },
    },
});

An override changes only the selected command's shortcut key. Its callback, environment, command identity, matching order, and all unaffected default shortcuts remain unchanged.

Backward compatibility

•  new ShortcutPlugin()  continues to use all built-in shortcuts.
•  new ShortcutPlugin(undefined)  continues to use all built-in shortcuts.
• Passing a  ShortcutCommand[]  continues to replace the complete built-in command list.
• Existing shortcut matching behavior and precedence are preserved.

API changes

Exports:

•  ShortcutPluginOptions

Shortcuts are exported so we can build entire shortcut list in consumer apps
