Add opt-in retained GDB and objdump summaries using the shared analysis-view layer. Preserve default complete Evidence, ordered records, provenance and completion facts. Validate real Bash disassembly, whole-client context costs, CLI publication and cleanup; retain the original measured cohorts and explicit coverage limitations. Closes #5584.
