Probe v2.4.0

Added

• Import a Postman environment JSON file from the Desktop Environment Manager or
  environment switcher, including collections without environments. Secret-marked
  values use the native credential store; YAML contains only secret declarations. Compatibility warnings require confirmation before writing.

Fixed

• Clarify when Postman imports preserve existing credentials, and avoid partial-secret
  warnings for interrupted imports containing only empty or null secret values.
• Accept Postman environment exports with variable descriptions in object format.
• Keep Delete working in the Environment Manager and the request tree after a
  confirmed deletion by selecting the next item, or the previous item when the
  deleted one was last, and returning focus to the list.
