Narrow Section 26 hyphen rule to drop only predicate-position cases

The original rule said to strip hyphens from compound modifiers
uniformly. That produces ungrammatical English in attributive position:
"a high quality report" is wrong; "a high-quality report" is correct.

The actual AI tell is uniform hyphenation INCLUDING in predicate
position ("the report is high-quality"). Humans typically hyphenate
attributive use only and drop the hyphen when the compound follows
the noun.

Reworded the Problem statement to spell out the attributive-vs-
predicate distinction. Reworked the Before/After so the same compound
modifiers appear in both positions, demonstrating that only the
predicate-position hyphens get dropped.
