fix(dist): stop USER_OWNED_EXCLUDE from filtering nested directories

The copytree ignore lambda in _copy_dist_payload applied USER_OWNED_EXCLUDE
recursively at every directory depth. This caused nested directories whose
names matched exclude entries (bin, logs, cache, etc.) to be silently dropped
during distribution install/update.

Fix: only apply USER_OWNED_EXCLUDE filtering at the root of the staged tree,
matching the two-tier pattern used by _clone_all_copytree_ignore and
_default_export_ignore in profiles.py.

Add 5 tests covering nested bin/logs/cache preservation and top-level
filtering still working.

Fixes #37954
