feat(parser): add test for Markdown to HTML conversion #331

- Added `MarkdownToHtmlConverterTest` to verify conversion of markdown to HTML.
- Updated `MarkdownToHtmlConverter` to handle `<THOUGHT>` and `<PLAN>` tags.
- Simplified `SketchToolWindow` panel initialization.
- Refactored `CustomLLMProvider` logic for plan model updates.
