Release 0.16.0

Added

• Merge supporting website (hosted at https://solid-select.com) into this
  repository for easier maintenance. Leverage it also for testing changes to the
  library. The site can be built and run locally using mise build:site and
  mise dev:site.

Fixed

• Fix duplicate options being suggested for creation when input has trailing
  spaces and filtering is enabled. Input is now trimmed before filtering to
  ensure it matches the creation existence check logic.
