Task #27: Double-click auto-move — best_destination() finds optimal target (foundation over tableau); handle_double_click() fires MoveRequestEvent. Task #28: Hint system — find_hint() returns first legal from/to/count triple; H key tints the source stack HintHighlight (yellow pulse via tick_hint_highlight). Task #29: No-moves detection — has_legal_moves() checks stock/waste/all face-up cards; check_no_moves system fires InfoToastEvent("No moves available") once per stalemate (debounced so it fires only once until the state changes). Task #30: Forfeit — G key fires ForfeitEvent; StatsPlugin records abandoned game, persists stats, starts a new deal. Task #37: Mute-all (M) and mute-music (Shift+M) toggles; MuteState resource applied in apply_volume_on_change. Task #39: Daily challenge HUD constraint label (time limit / target score). Task #40: Undo-count HUD label; amber colour when undos > 0. Task #44: Win-streak and level line on pause screen. Task #48: Undo sound routes UndoRequestEvent → lib.flip audio channel. Task #49: Onboarding banner rich-text key highlights — D and H rendered as orange KeyHighlightSpan children so they stand out from body text. Also registers CursorPlugin in solitaire_app (tasks #31/#32 wire-up). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
