Commands: Transform Each, artboards and more refuse a boolean or number given as text

object.transformEach refused reflectX, reflectY, random and copy given
as text, but read strokes, corners, objects and patterns given as text
as the key left out. With Scale Strokes & Effects on,
{"scaleH": 200, "scaleV": 200, "strokes": "false"} scaled the stroke,
recorded an undo step and kept the params for Transform Again, which
repeated the call. artboard.rearrange, artboard.move and
artboard.duplicate read their patterns option the same way, and
artboard.setProps reads its patterns, strokes and corners options the
same way.

These commands now refuse such a value with "`<key>` must be true or
false" before they change anything. So do the other options and
numbers of artboard.setProps and artboard.move, the art of Duplicate,
Copy and Cut Artboard, the shape commands and path.create, path.close,
path.setHandle, path.moveAnchors, the Pencil, Curvature, Reshape
Segment and Blob Brush options, text.create, text.createInPath,
text.setRangeStyle, text.editRange, text.getRange, text.touchType,
text.areaOptions, type.step, the font size steps,
type.opticalMarginAlignment, type.systemLayout, type.fractionalWidths,
type.ruby, the symbol and swatch commands, the Appearance panel's
commands, the gradient and freeform gradient commands, Shape Builder,
Live Paint, Image Trace, the opacity of object.setProps, the radius,
sides and relativeRadii of object.setLiveShape, the reference point of
object.setBounds and the artboard of Align, Distribute and Distribute
Spacing. They refuse a number given as text with "`<key>` must be a
number, not <value>", and a gradient stop's tint with "stop <n>:
`tint` must be a number". A null still reads as the key left out.

 A step can use an earlier step's result, in `run` as in the `command_batch` tool. A parameter string that is exactly
 `$N` or `$N.path` takes that value from the result of step `N` (counting from 0, in the order they ran; `run --in`'s
 open isn't a step), and `$last…` from the step before. A path goes into objects by key and arrays by index:
