### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Not-null inference replaces candidate slots with NULL and folds each
predicate, so wide, deep, or high-slot expressions can make rewrite rules spend
excessive time in repeated replace and fold work. Aggregate not-null inference
also needed to handle multiple aggregate outputs conservatively instead of
inferring from all aggregate arguments as one set.
This change adds a shared bounded guard for not-null inference, reuses it
from aggregate inference, and lets general callers skip only expensive
predicates while preserving the original query predicates. It also reworks join
inference to compute nullable-rejecting slots once and reuse them for both
sides, and makes aggregate inference require a common inferred not-null
predicate across supported
aggregate functions.
