📝 WalkthroughWalkthroughThe editor now supports PowerShell syntax aliases, safely flattens lowlight output, and refreshes decorations when code-block content or structure changes. Vitest coverage validates token preservation, language aliases, highlighting, and performance. ChangesCode block highlighting
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: ⚪ Minimal · up to This change adds PowerShell syntax highlighting and safer nested AST text extraction for editor code blocks; no actionable merge-blocking risk remains, so it is merge-ready after normal checks and review.

Replace any with typed Lowlight and HAST contracts.
parseNodes, getDecorations, LowlightPlugin, and helper functions use any despite the package's strict TypeScript configuration. Use maintained Lowlight and HAST types, and use unknown where the code only checks a value's type.

Test the decoration-refresh path.
This suite imports only parseNodes. It does not create LowlightPlugin or apply a transaction. Add plugin-state tests for a code-block content replacement while selection is outside the block, and for code-block insertion or replacement. These cases execute the new codeBlockChanged path.
As per coding guidelines, **/*.{test,spec}.{ts,tsx,js,jsx}: All features require unit tests using the existing test framework per package.
