W1 context column: heading-path prefixes in dedicated FTS column, default off

Measured on LegalBench gold: weight 2 is slightly negative (R@4 0.2865
to 0.2763) because headings are regex-guessed on plain text and queries
do not use heading vocabulary. Column ships default-off for the product
skeleton lane, where true heading paths exist.
