Validate loop boundary conditions

When implementing iterative algorithms, ensure comprehensive handling of edge cases and boundary conditions. This includes:

1. Using while loops instead of if-else chains for repetitive operations
2. Explicitly handling overflow/underflow scenarios
3. Validating both start and end conditions
4. Testing with boundary values

Example - Before (problematic):

if (strings.endsWith(normalized_name, "/")) {
    normalized_name = normalized_name[0 .. normalized_name.len - 1];
} else if (strings.endsWith(normalized_name, "\\")) {
    normalized_name = normalized_name[0 .. normalized_name.len - 1];
}

Example - After (robust):

while (strings.endsWith(normalized_name, "/") or 
       strings.endsWith(normalized_name, "\\")) {
    normalized_name = normalized_name[0 .. normalized_name.len - 1];
}

This approach prevents issues like:

• Missed cases in chained conditions
• Integer overflow/underflow in calculations
• Incomplete processing of repeated patterns
• Boundary condition errors

When implementing iterative algorithms, always consider:

1. What happens at zero/empty input?
2. What happens at maximum values?
3. Can the operation need to be repeated?
4. Are all edge cases handled explicitly?
