Subject: [PATCH] FIX: Add error handling to FPM process count function

Fixed line 282 in lib/php-detector.sh:
- Changed: ps aux | grep | grep -v | wc -l
- To: local count=$(... || echo 0) with explicit echo

This prevents pipe failure with set -eo pipefail if no FPM processes
match the search pattern. Function now returns 0 instead of crashing.
