      DRIVERS-3321:
      Summary of necessary driver changes

      • Rename QE "text" APIs to "string"
        • rename TextOpts to StringOpts
        • rename "TextPreview" algorithm to "String"
        • add queryType "prefix"
        • add queryType "suffix"
        • document "prefix" and "suffix" as stable.
      • Update spec and prose tests for the new names.
      • Upgrade to libmongocrypt 1.19.1+ to support the new names.

      "substring" will be added in DRIVERS-3540 pending server changes.

      "prefixPreview" and "suffixPreview" are still experimental and planned for removal in DRIVERS-3548.

      The API renames break compatibility of experimental QE APIs. This is expected to be OK in a minor release since APIs were documented as "unstable API and subject to backwards breaking changes".

      Commits for syncing spec/prose tests

      • 2026-06-16: changed scope to only add "prefix" and "suffix" without dropping "prefixPreview" and "suffixPreview". Motivated by slack thread
