fix(ci): add ambient type reference for oxlint-config imports

The TS build failed because private.ts imports from @rnx-kit/oxlint-config/*
which ships no type declarations. Add a triple-slash reference so the
existing types.d.ts is always in scope, even when other packages compile
this file with their own tsconfig.
