Laravel Process::fake() with ARRAY-form commands silently falls through to the REAL system — a start-anchored pattern like 'pgrep*' never matches (Symfony escapes to 'pgrep' '-f' …), so use '*pgrep*' + preventStrayProcesses().

Found by flower-191-horizon-reload-worker while writing tests for flower:horizon-reload (brief #191). When Process::run() is called with array-form (['pgrep','-f',pattern]), Process::fake(['pgrep*' => …]) does NOT match because the faker compares against Symfony's escaped command line ('pgrep' '-f' '…'), which begins with a quote — so a prefix-anchored key silently misses and the call executes for real. The worker fixed its own tests with '*pgrep*' + Process::preventStrayProcesses(). Suggested follow-up: audit the suite for other Process::fake usages with array-form commands + prefix-anchored patterns (same silent-fallthrough risk), and consider adding preventStrayProcesses() to the base TestCase so any unmatched fake errors loudly instead of hitting the real system.
