feat(search): add Xquik X search provider (#11370)

Merged into release/v3.8.51 via batch validation: xquik provider suites green on the combined tree (193 node:test assertions incl. your 7 new cases), check:provider-consistency OK (353 canonical providers), static gates green. Well-scoped fallbackOnly X-provider with clean citation building — thanks @kriptoburak!
