Review Comment:
Fixed in b6ad0f2571d. MATCHED-only changelog MERGE now treats every
surviving INNER JOIN row as a match, including NULL-safe matches on nullable
keys. MERGE with INSERT branches projects a non-null target marker before the
outer join and resolves its null-extended output by ExprId. User expressions
retain their original scope so a same-named source column is not shadowed by
the private marker.
The exact single-key SQL reproduction now updates the NULL-key value from 20
to 99 and deletes it (row count 0). Validation passed: FE build/Checkstyle, 38
related FE unit tests, and 9 Paimon regression suites including all six
existing write suites containing MERGE. The new generated/replayed SQL golden
covers NULL single/composite keys, ordinary versus NULL-safe equality, branch
priority, INSERT-only paths, duplicate-match rejection with unchanged rows, and
marker-name collisions.
A separate constant one-row multi-key NULL-safe JOIN issue also reproduces
in an internal OLAP SELECT. It is recorded in the PR's validation limits; the
composite-key DELETE test uses a multi-row source with an unmatched control.
