feat: allow custom views directory for templates and markdown

- Add viewsDir parameter to LiteNode constructor
- Modify MarkdownHandler to accept custom views directory
- Update extendResponse to use configurable views path
- Pass viewsDir through handleRequest chain
- Maintain backward compatibility with default "views" directory
- Update TypeScript definitions to reflect new constructor params
