Subject: [PATCH] OPTIMIZE: Regex Pattern Library (OPT-12)

Consolidates repeated grep patterns and file checks into reusable helper functions.
Provides consistent pattern matching across the script and reduces duplication.

OPT-12: Regex Pattern Library (25 min effort)
- grep_wp_config_define() checks if wp-config has a specific define
- grep_disabled_wp_cron() checks if WP-Cron is disabled (true value)
- grep_enabled_wp_cron() checks if WP-Cron is enabled or commented out
- grep_in_crontab() safely searches crontab for a command string
- grep_wordpress_path() validates WordPress installation directory
- Impact: 3+ repeated grep patterns consolidated, consistent matching

Benefits:
- DRY principle enforcement
- Pattern updates in one place
- Consistent error handling
- Easier to test and maintain

Code Metrics:
- Lines added: +30 (5 pattern functions)
- Pattern duplication: Eliminated
- Code clarity: Improved (grep_* prefix makes purpose clear)
- Test: bash -n validation passed

Total optimizations implemented: 14 of 20
