### What problem does this PR solve?
Issue Number: N/A
Related PR: #60386
Problem Summary: MultiCastDataStreamer already shares pulled blocks through
the column copy-on-write contract. The previous pull path still cloned every
column for each consumer through _copy_block(), which added unnecessary
per-consumer allocation and copy work. The copy-on-write assertion changes and
regression coverage from the original attempt are already present on current
master, so this change keeps the pull completion accounting in _finish_pull()
and returns the shared block directly.
