Exhaustive audit of every MDX file in docs/ against skill references
and package source code. Every API signature, default value, flag,
and technical claim verified against ground truth.
New docs pages for the three packages extracted from core (#1755, #1756,
#1757), wired into the Packages nav after @hyperframes/core. Each covers
when-to-use, exports, and API with cross-links. Core's parser/lint sections
now point at the dedicated packages and its Related Packages lists all three.
