Alt-drag, Cmd+Opt-drag and Free Transform on a copy duplicate with
`inPlace: true` for every layer, but the flag only changes anything for
an artboard. With in-place duplicates now refused on strict .atn export,
a recorded copy of a plain layer could no longer be exported, although a
plain Duplicate replays it exactly. Recording now drops `inPlace` when no
copy is an artboard, as `layer.select` already rewrites its recorded
params.

Photoshop's Duplicate Layer has no in-place flag, so `layer.duplicate
{"inPlace": true}` was exported as a plain Duplicate and replayed with
the artboard copy beside the original. Strict export now fails on it and
skipUnsupported reports it, as for a Close with a document target.
