ci: bump version to v0.4.3

Map raw backend response (evaluation/continuationMoves) to frontend
model (eval/winChance/continuations). Add getFenHistory() call after
loading a game or PGN so runAnalysis() gets per-ply FEN history and
triggers analyzeGame() instead of falling back to single-position
analysis. Remove !hasAnnotations guard so positionAnalysis card shows
even when a game is loaded.
