search() now unwraps { results: [...] } -> [...] internally (same
pattern getAll() already uses), so callers always get Array<Memory>.
Removes redundant unwrap logic from integration test helpers and
search.test.ts that caused TS2339 'Property results does not exist
on type never' — the false branch of Array.isArray() was unreachable
since search() is typed as returning Array<Memory>.

v3 search returns {results: [...]} instead of a bare array.
Updated waitForSearchResults helper and search edge case tests
to unwrap the v3 envelope.
