### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary: This PR extends the new parquet reader with page-level skip
support and the first set of observability counters needed to validate it. Page
index planning now produces page skip plans consumed by Arrow page readers,
avoiding double skip with row-range pruning. The reader profile now reports
scheduler/read path counters, reader read/skip/select rows, Arrow RecordReader
timing, materialization timing, page skip pages/bytes, and row group/page index
planning timing. Temporary implementation plan docs were removed after the
feature work landed.
