 * ## Browser spellcheck integration extension for native spelling correction
 *
 * Provides seamless integration with browser's native spellcheck functionality through context menu interactions.
 * Enables right-click spelling suggestions on misspelled words while preserving editor functionality and text input
 * handling. The extension bridges browser spellcheck capabilities with the editor's text manipulation system.
 *
 * **Enable:** `editor.setOption("spellcheck", true)` (enabled by default)
 * or configure it during editor initialization in the options object.
