"""qs-launch — wofi-based launcher modes: emoji pick, calculator, DuckDuckGo search.

Subcommands:
  emoji   feed a curated emoji list into wofi --dmenu, copy the picked emoji
  calc    type an expression in wofi, evaluate with qalc, copy + toast result
  search  type a query in wofi, open DuckDuckGo in the default browser

All binary paths are injected via $QS_* env vars by the .local/bin/qs-launch
wrapper so execution works regardless of PATH (same pattern as qs-bt's
$BLUECTL). When no DISPLAY/WAYLAND_DISPLAY is present, wofi can't open, so each
mode exits silently with code 1.

# Curated emoji list: "<char> <shortcode>". Searchable by name, output splits
