Swift-Markdown-engine

Added

• ==highlight== inline markup — configurable via MarkdownEditorTheme.highlightColor (default translucent orange); nested emphasis/code parsed inside.
• Formatting bus — MarkdownEditorBus gains highlight + nine actions (strikethrough, inline code, blockquote, un/ordered list, link, code block, horizontal rule, image), each with a matching didMarkdown* coordinator action and word-boundary auto-wrap (wrap the word under the caret when there's no selection).
• NativeTextViewWrapper.onBuildContextMenu — embedder hook to build the right-click menu; the engine ships none (API-only).
• NativeTextView.isCursorExcluded — predicate that suppresses the edit-mode I-beam over an exclusion zone (e.g. a floating formatting toolbar).
• MarkdownEditorBus.findQuery / findResults — query-based in-document find that matches the engine's displayed text (correct where it differs from source).

Changed

• No built-in right-click "Format" menu anymore — menus are embedder-supplied via onBuildContextMenu. The system rich-text "Font" submenu is stripped from the default menu (font traits don't apply to Markdown).

Fixed

• Blockquote removal no longer doubles trailing newlines.
