Use the shared artifact file owner for kernel report reads, preserving the
physical outcome and exact retry lease through failed close and recovery.

Fixes#4926

Inspect selected fields in existing captures through shared CLI/MCP Evidence.
Page matching frames without changing dissection or two-pass read coverage;
retain failed descriptor/process cleanup ownership and reject excess admission.
Verified with real TShark 4.0.17 and 4.2.2, public Wireshark recordings,
owned HTTP application traffic, real CLI/MCP workflows and schema checks.
