`Name:` read a name only up to the first period, so `Name:Sales.Q1` looked up `Sales` and
treated `Q1` as a method, and a workbook name called Sales.Q1 could not be used in a macro,
alone or as `Name:Sales.Q1.cell(1,1)`.
The name now runs through periods, and the longest defined name or table that exists and ends
at a period (or the end) is used; what follows is read as methods. So `Name:Data.row` is a
name called Data.row, and `Name:Sales.offset(1,0)` still moves Sales. When no name matches,
the error names the text before the first method, and a bad method after a dotted name is
still refused. Tests cover direct resolution, reference parameters, `$ref` and `{{...}}`,
with and without a chained method.
col("...") always matched against the first row of the range, whatever
its header flag. On an input declared without a header row,
Input.col("Amount") silently picked the first column whose first data
cell read "Amount". After .data, the natural Input.data.col("Amount")
failed, because the first row was then a data row. The header row is
now carried through data, and col("...") is refused with a message when
there is none (an input without a header, a Name: base, or after any
other method).
is_token looked only at the leading identifier, so on a workbook with a
sheet called Output (or Row, Column, or the name of a declared input),
"Output!A1:B2" was read as the Output token, and the step failed with
"the macro has no output anchor" or "unexpected '!A1:B2'". This hit
reference keys, $ref and {{...}} alike, including references the
recorder writes for other sheets. A base followed by '!' is now a sheet
name, and the text resolves as a plain reference.
Opening a workbook accepted a macro whose format version `v` was above MACRO_VERSION. Serde
dropped the fields this build doesn't know, and the next save wrote the reduced macro back
with `v: 2`, so a newer build would read it as a complete version 2 macro.
A version above MACRO_VERSION is now refused by Macro::check_limits, and parse_macro checks
the raw `v` before reading the steps. Such a macro takes the existing per-macro path: it is
left out with the usual single warning (which now names a newer format), and the rest of the
workbook opens. Tests cover JSON and xlsx hidden names, with current and missing versions as
controls.
