hermes - 💡(How to fix) Fix hermes dashboard --status reports stale PIDs on macOS [1 pull requests]

Problem

On macOS, hermes dashboard --status reports phantom PIDs that no longer exist.

$ hermes dashboard --status
3 hermes dashboard process(es) running:
    PID 56731
    PID 56740
    PID 61666

$ ps -p 61666
PID TTY           TIME CMD
# (empty — process gone)

Root Cause

_find_stale_dashboard_pids() in hermes_cli/main.py uses pgrep -f on macOS, but macOS pgrep does not support -f (full command line match). This causes incomplete matching and stale PID entries.

Linux path uses /proc/<pid>/cmdline which works fine.

Suggested Fix

Replace pgrep -f with ps -A -o pid=,command= + Python filtering on macOS.

result = subprocess.run(["ps", "-A", "-o", "pid=,command="], ...)
for line in result.stdout.splitlines():
    pid, cmd = line.strip().split(None, 1)
    if "hermes dashboard" in cmd:
        pids.append(int(pid))

Environment
