Goal

As a support engineer examining a customer's pstack, top -H, or perf output, I need each thread to have a meaningful OS-visible name so I can immediately tell what it does without correlating raw thread IDs against internal data structures.

Every thread created by ns-slapd should get a name via pthread_setname_np. Workers become worker-0 through worker-N, the listener becomes listener, replication threads become repl-prot, repl-inc-res, and so on. All names must stay within the Linux 15-character limit (16 bytes with the null terminator).

Acceptance criteria

• Verify every worker thread shows as worker-N in /proc/<pid>/task/*/comm
• Verify the listener thread, replication threads, and other named threads appear with correct names in ps -eLf and top -H output
• Verify all names are 15 characters or fewer
