fix(worker): classify ack interop failures at the COM call; ignore late completions
Address review of the #164-#166 fixes:

- The HRESULT check could not tell interop from programming errors
  (a managed ArgumentException already defaults to 0x80070057). Wrap each
  MXAccess call (AuthenticateUser, AddItem, Advise, Write) in a narrow
  filter that converts an interop failure to a private marker exception,
  and catch only that marker, so exceptions from the writer's own code
  (argument checks, caching, the pump) propagate.
- A late OnWriteComplete for a dropped handle recreated the cache entry
  that DropItem removed. The writer now records completions only for item
  handles it holds on its live registration.
- The item-handle-reuse probe now asserts that handles within one
  registration strictly increase, so a rerun is a regression check.
