Format IN/NOT IN lists and add tests

Add formatting for SQL IN/NOT IN value lists and related tests. Introduce InPredicateCollector to collect InPredicate nodes from TSql fragments and update FormattedScriptGenerator to expand single-line comma lists into indented multi-line blocks for better readability. Add two tests (RecordingInClause, RecordingNotInClause) and their .verified.txt expectations. Update readme snippet source links to reflect new line ranges.
