fix(engine): single-word rule connects along the play line

Bumps the engine to scrabble-solver v1.1.1, where a single-word-per-turn play must form its word along its own line through an existing tile: a multi-tile play that touches the board only perpendicular to itself (the contour РЮМ/КЕД/ОР cases) no longer connects. For a single tile that abuts the board on both axes the engine now plays the higher-scoring legal orientation instead of the geometrically longer one (playDirection), so a real word is never rejected in favour of a non-word. Reworks the single-word solver/engine tests for the corrected rule (no longer a superset of standard play) and updates ARCHITECTURE/FUNCTIONAL/PRERELEASE.
