v18.0.2 - Exceptional clean up

This is a minor patch release of uSync.Complete for Umbraco v18, it cleans up some internal exceptions (that don't surface unless you are tracing - but never-the-less fire a lot internally). and adds a refresh of the content after a pull request.

Fixed

• #301 - Publisher: after a Pull from server, an open content editor now refreshes
  automatically instead of showing the pre-pull data. The pull actions dispatch an
  entity-updated event so the workspace reloads the freshly pulled content.
• #304 - Reduced harmless first-chance InvalidCastExceptions during push/pull: the
  dictionary value lookup now checks for a JsonElement before calling
  TryConvertTo, avoiding a cast that was thrown and immediately caught inside
  Umbraco. Behaviour is unchanged; the exceptions were only visible under a
  debugger or first-chance exception logging.
