Phases 1-3 of library/application boundary cleanup:
Phase 1: Remove dead code (150 lines)
- Delete local word-wrap (all callers already used cl-tty.box:word-wrap)
- Delete parse-markdown-spans, render-styled, parse-markdown-blocks,
syntax-highlight (all unused — view uses cl-tty.markdown directly)
- Replace tests with cl-tty.markdown equivalents
Phase 2: Migrate theme to cl-tty.theme (250 lines removed)
- Replace *tui-theme*/*tui-theme-presets* with *theme* + define-preset
- theme-switch/theme-save/theme-load delegate to cl-tty.theme
- theme-color is now a 3-line wrapper
- Added save-theme/load-theme to cl-tty.theme (38 lines added there)
Phase 3: Fix dialog arrow navigation with select-handle-key
- Replace broken manual key dispatch with cl-tty.dialog:select-handle-key
- The old code had a dead (and ch (graphic-char-p ch)) — the and result
was discarded, so every unhandled key ran (code-char key-code) against
the filter unconditionally, inserting garbage on arrow keys
