At the RSTL timeout in replication_coordinator_impl.cpp (v7.0), getGlobalLockManager()->dump() emits log id 20521 with per-holder desc, connectionId, client IP, and opid but the debugInfo field is empty in practice. Locker::setDebugInfo is called at commands.cpp:914 on the sync run path only, so it does not cover async paths, transactions, and background contexts. Attribution still requires cross-referencing slow-op logs by ctx after the fact.

Populate debugInfo at dump time from each Locker's OperationContext / CurOp state:

• ns
• redacted command
• queryHash
• planCacheKey
• planSummary
• secs_running
• numYields
• storage.data.bytesRead

This would help triage AF-895 failures.
