fix(tui): render inline markdown formatting with ANSI codes

Block-level renderer methods (paragraph, heading, blockquote, list) were
using raw token.text instead of this.parser.parseInline(tokens), causing
bold, italic, and inline code to never render. Add table renderer with
aligned columns and box-drawing separators. Remove unused marked-terminal
dependency (incompatible with marked v17).
