Fix#1: Duplicate trap handlers with missing flock unlock (CRITICAL)
Problem: Line 32 set trap with flock unlock, line 373 overwrote it
Result: Flock never unlocked, lock file stays locked
Fix: Consolidated into single trap with flock unlock
Impact: Prevents future invocations from being blocked
Fix#2: User extraction cache being bypassed (10 locations)
Problem: get_user_from_path_cached() existed but 10 places called
extract_user_from_path() directly, bypassing cache
Result: For 200 sites, user extraction done 200+ times without cache
Fix: Replaced all 10 direct calls with cached version
Locations: Lines 1308, 1364, 1687, 1836, 2051, 2180, 2369, 2537, 2700
Impact: Eliminates redundant stat calls for user extraction
Fix#3: Removed duplicate first trap
Problem: Line 32 had first trap that was immediately overwritten
Fix: Removed with note that single trap at line 373 handles both
Impact: Cleaner code, prevents confusion
