Classify clean settle + missing target as transient (settled-no-deliverable)
and re-invoke once with a corrective write-tool prompt, instead of permanent
MISSING_TARGET failure.
Fresh step invocation is limited to provider terminated/connection plus
a missing target, or an explicit runner failure. A deliverable already
on disk is accepted and never overwritten.

Treat process-0 plus terminated/Connection error/auto_retry_end as a
provider transient. Permanent missing deliverables stay fail-closed and
are never reconstructed from truncated write arguments.
