Tidy Transformer_NonRecursive: move Discard placeholder comment to the filter site

Fix Transformer_NonRecursive corrupting the tree on a non-last Discard

When a callback returned Discard, Transformer_NonRecursive did not push a
result for that node, but a parent still sliced `stack[-len(children):]`.
For a discarded node that is not the last child processed, that slice
over-consumed the stack and pulled an unrelated sibling into the wrong
parent -- e.g. `start[keep, wrap[drop]]` came back as
`start[wrap[keep]]`, silently dropping and re-parenting nodes. The base
Transformer (documented to give the same result) was unaffected.

Push discarded results as placeholders so every node consumes exactly
`len(children)` stack slots, and filter the placeholders when building a
parent's args. A wholly-discarded tree now returns None (this also covers
the root-discard crash) instead of mis-unpacking an empty stack.
