fix: pgrep -c flag missing on macOS BSD pgrep (was flooding error log)

The getRunningClaudeCount() circuit-breaker used 'pgrep -c -f' which
worked on GNU/Linux but exits 2 with 'usage: pgrep' on macOS, since
BSD pgrep has no count flag. The count was always returning 0 via
the catch-block, silently disabling the concurrency circuit breaker,
and producing ~76 'usage: pgrep' lines per session in
~/.pm2/logs/yolo-agent-error.log.

Replace with portable 'pgrep -f ... ' + line count in JS, and
redirect stderr to /dev/null via stdio so any future pgrep stderr
output doesn't pollute pm2 logs.
