fix: ANSI parser now correctly renders green colors in SVG

The  parser split ANSI codes like  into
individual elements  but compared each element
against the full string , which never matched. No
ANSI colors were ever rendered - all text was white.

Now uses index-based parsing: detects  → reads next two
elements (, ) to extract the 256-color number.

Changes visible in demo SVG:
- , , , , , ,  → green
- Unselected items, prompts → light green
- Selected items, headings → bold white
- Commands → white with green  prefix
