refactor(client): unify duplicate YAML parsers into YamlParser (#560)
Extract shared YamlParser utility (client/scripts/util/yaml_parser.gd) with parse() for nested typed dicts and parse_flat() for dotted-key string format. UIStrings._parse_yaml() and ChecklistEvaluator's inline parser both delegate to YamlParser, removing ~140 lines of duplication. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
