Add COUNTIF/COUNTIFS, SUMIFS, AVERAGEIF/AVERAGEIFS, MAXIFS/MINIFS, MATCH/XMATCH, CONCATENATE, ABS, MOD, MEDIAN, IFS, SWITCH, POWER, SQRT, PRODUCT, SUMPRODUCT, CEILING, FLOOR, STDEV/STDEVP/VAR/VARP (and .S/.P aliases), MODE (and MODE.SNGL), RANK (and RANK.EQ), COUNTBLANK, IFNA, ISBLANK/ISNUMBER/ISTEXT/ISERROR/ISNA, DAYS, NETWORKDAYS, WORKDAY, DATEVALUE, EXACT, CHAR, CODE. Engine support: ParameterType.Group preserves argument boundaries for variadic range/criteria pairs and arrays; FunctionStore.Add registers dotted-name aliases; the parser accepts dotted function names; CellData comparisons are case-insensitive and MatchesCriteria handles =/<> operators and wildcards. Fixes a latent CHOOSE bug where range arguments were flattened. All function results verified against Excel.
