* fix(cancellation): preserve caller abort reason in cancellation errors
Several application, provider, and MCP boundaries constructed
AnalysisCancelledError, ArtifactReaderFailure, or
DetachedPgpSignatureError for an already-observed or newly-observed abort
without passing the caller's signal.reason as the error cause. The typed
result then reported cancellation with an undefined reason even though the
exact object supplied to AbortController.abort(reason) was still available.
Pass signal.reason as the cause at each producing cancellation site:
JavaScript artifact reconstruction and file abort checks, derived MCP
operation checkpoints, detached PGP verification, ASAR listing admission,
Dart AOT inspection and its provider guard, evidence-file analysis views,
binary layout and recorded crash admission, WASM inspection admission,
and the Kuna shared assembly-index wait.
Cancellation classification and cleanup behavior are unchanged.

* test(cancellation): assert the exact caller reason identity
Copied reasons satisfied toMatchObject, so the tests would pass even if the
caller's abort reason were replaced by a structurally equal copy. Capture the
rejection and assert the cause is the same object.
