Uses ctypes (stdlib, no new dependency) to call prctl on Linux and pthread_setname_np on macOS so the process shows up as 'hermes' instead of 'python3.xx' in ps, top, htop. No-op on Windows (hermes.exe is already the visible name). Closes NousResearch#35108
Adds setproctitle as a core dependency (pure C, very stable) to change
the process title from 'python3.xx' to 'hermes' on Linux, macOS, and BSD.
Strategy:
1. setproctitle.setproctitle('hermes') — works everywhere, no 15-char limit
2. Fallback: ctypes prctl(PR_SET_NAME) on Linux (stdlib)
3. Fallback: ctypes pthread_setname_np on macOS (stdlib, kernel thread name)
Closes NousResearch#35108

Summary
On Linux and macOS,
hermesshows up aspython3.11(or whatever Python version) in process monitoring tools likeps,top, andhtop. This is confusing — users naturally look for the app name, not the interpreter.This PR sets the process title to
hermesso the process is immediately recognizable.Changes
hermes_cli/main.py: added_set_process_title()— tries three strategies in order:setproctitle.setproctitle("hermes")— cross-platform, works on Linux/macOS/BSDprctl(PR_SET_NAME)via ctypes (Linux, stdlib)pthread_setname_npvia ctypes (macOS, stdlib — kernel thread name only)Called at the very top of

Notes
setproctitleis pure C, very stable, and already packaged for all major distros.
