fix(errors): preserve caller abort reasons at admission (#5671)

* fix(errors): preserve caller abort reasons at admission

Keep the opaque caller reason on reverse, pcap, and SQLite cancellation,
and leave a recognized physical digest or command failure in place when a
late abort is also observed.

Fixes #5670

* fix(reverse): keep a foreign digest ABORT_ERR as an adapter failure

Treat ABORT_ERR as cancellation on the command boundary, where that code
already meant an aborted provider process. A digest or stat rejection with
the same code stays a physical adapter failure unless the caller signal
is aborted. Cover aborted command EACCES, ETIMEDOUT, and ABORT_ERR with
and without captured output.
