Condensed array display + per-scope column widths + MIT license

- Array element structs render without { } braces (condensed display)
- [N] separators show element indices within arrays
- Per-scope column width calculation (nested elements use tighter spacing)
- Array headers show struct[N] for struct arrays
- [N] separators are not interactive (no hover/click highlight)
- Dynamic type column width (min 8, max 14)
- PE32+ sample data with full headers, DataDirectory[16], SectionHeaders[4]
- Added MIT license
