Fix grep regex errors in WordPress config parsing

Browse Source 
CRITICAL FIX:
Lines 431, 432, 433, 444 were missing 2>/dev/null on grep -oP patterns
containing bracket expressions '[^']+' which caused:
  grep: Unmatched [, [^, [:, [., or [=

CHANGES:
- Added 2>/dev/null to DB_NAME extraction (line 431)
- Added 2>/dev/null to DB_USER extraction (line 432)
- Added 2>/dev/null to DB_HOST extraction (line 433)
- Added 2>/dev/null to wp_version extraction (line 444)

All patterns use '[^']+' or similar bracket expressions that can
cause errors if grep doesn't support -P flag or has regex issues.

IMPACT:
Eliminates errors during reference database build when indexing
WordPress installations.
