Subject: [PATCH] Standardize mysql-query-analyzer.sh menu validation and
 colors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

IMPROVEMENTS:
- Added input validation for menu choice (0-6) with retry loop
- Changed color codes from ${GREEN} to ${CYAN} for consistency with standard
- Added explicit break statements for all valid selections
- Removed wildcard case that silently accepted invalid input
- Improved user prompt to show valid range (0-6)

VALIDATION DETAILS:
- Choice: Only accepts 0-6, rejects invalid with clear error message
- Retry loop: User stays in menu until valid choice is entered
- Option 0: Back to menu (no function execution)
- Options 1-6: Execute analysis function then break from loop

MENU STANDARDS COMPLIANCE:
✓ Input validation (CRITICAL)
✓ Default values (N/A - menu only)
✓ Color codes (IMPORTANT - changed to CYAN)
✓ Error messages on invalid input (IMPORTANT)
✓ Retry logic for failed validation (IMPORTANT)

Lines modified: ~20 (input validation + color standardization)
