### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary: SegmentIterator kept a separate `remaining_conjunct_roots`
list in addition to `common_expr_ctxs_push_down`. Both represented the same
residual common expression state, so index pruning paths had to keep them
synchronized and could drift when an expression was removed after index
evaluation. This change removes the duplicated `remaining_conjunct_roots`
plumbing and uses `common_expr_ctxs_push_down` as the single source of residual
common expression state for condition cache decisions, lazy materialization
column extraction, and expression execution checks.
