bench: fix PHP arrow functions (fn()=> requires 7.4+), PASS=20/20 on PV

Browse Source 
- Replace fn()=> with traditional function() syntax in php_medium and php_large
- 8 arrow function occurrences fixed across processWords/statsArr/caesar/lookupOps/nested array_map
- Added diag_bugs.sh: diagnostic script for PHP pool exhaustion + ruby/medium cold anomaly
- bench_full.sh RUNID=9250986: PASS=20 FAIL=0 (was PASS=18 FAIL=2)
- ruby/medium cold=81549ms anomaly confirmed reproducible (3rd time), not a FAIL
- Added doc/report-2026-05-20-bench-php-analysis.md
