feat(flutter): token + asset sync from web; gen_tokens.dart

shared/fabledsword.tokens.json mirrors web/src/lib/styles/tokens.json; assets/error-copy.json mirrors the web's error-code copy table; assets/svg/album-fallback.svg mirrors the web placeholder. Together these give Flutter the same visual + copy starting point as the SPA. tool/gen_tokens.dart emits lib/theme/tokens.dart from the JSON; the generated file is committed so CI can verify the JSON and the Dart file haven't drifted (gate added in Task 21). tool/sync_shared.sh mkdirs the shared/ + assets/ destinations before copying so the script works on a fresh checkout (the original plan-text shape only mkdir'd assets/svg). pubspec.yaml assets block uncommented now that the three asset paths exist on disk.
