Implements the modern-backend with truecolor SGR, Unicode box-drawing (rounded/double/single), DECICM synchronized updates, OSC 8 hyperlinks, cursor style control, and hex color parsing. RED: 32 checks, 5 fail (class forward-ref + test bug) GREEN: 32/32 checks passing (100%) - backend/modern.lisp — escape generators + modern-backend class - backend/modern-tests.lisp — 16 test cases, 32 assertions - backend/package.lisp — updated exports - org/modern-backend.org — literate source
