fix(picker): pointer-width vtable offsets, COM apartment pairing, unconditional abort budget, and the full failure chain

Review round two on the in-process dialog:

- Vtable slots and out-pointers use koffi.sizeof('void *') instead of a
  hardcoded 8 - win32-ia32 (which Node and koffi both ship) would have read
  method pointers from the wrong address and crashed in-process before any
  fallback could run.
- runFolderDialog pairs every successful (incl. S_FALSE) CoInitializeEx
  with CoUninitialize in the outermost finally, releasing the dialog first;
  a failed init is deliberately unpaired. Pinned across fake-bindings and
  mocked-koffi suites.
- The abort close budget starts unconditionally: a worker hung before the
  showing notice (koffi import or COM init) now ends in terminate instead
  of a dangling promise; WM_CLOSE posting still waits for the thread id.
- A triple miss (dialog + pwsh + 5.1) surfaces an AggregateError carrying
  all three causes - the in-process tier's reason was previously
  unrecoverable from the final PowerShell error.
- The stray '=>{ ' formatter artifacts are normalized to real blocks.

Both stale note claims from the review are fixed: the DPI note's
Consequences no longer claims an ENOENT classification or zero new
dependencies, and the 2026-07-27 picker note's Windows bullet now names
the in-process primary and keeps the PowerShell chain as fallback (both
languages, pairings re-recorded).
