CompositeComponents are always strict and never log to file

[gpeairs]

For example, when build!(schematic; strict=:no) is called, then build! is called on each CompositeComponent's internal schematic, but

1. without the strict=:no setting
2. with its own SchematicLogger (which has log_dir=nothing so doesn't write to a file)

Both can be fixed factoring the inner with_logger block into a _build! function, so that build! calls that version instead of itself on composite components.

Same thing for plan and render!, most likely.
