“haonan”andCursor 524516cb56 fix(protocol): align Trace v2/v3 classification and hover steps
Require Trace v3 version const 3, reject mixed pages/states payloads, and
align TypeScript selection optionality with the generated schema. Trace v2
on main already records hover steps, so the frozen v2 schema must accept
them instead of dropping them during reduction.
