Consolidate String Reversal Implementations and Enhance Test Coverage

Description

Summary of Work

This pull request aims to address duplicate string reversal implementations and standardize the string reversal utility across the project.

Key Objectives:

• Consolidate two existing reverse_string implementations
• Ensure consistent error handling and implementation
• Maintain and expand comprehensive test coverage
• Improve code quality and reduce redundancy

Current State:

• Two separate modules (src/string_reversal.py and src/string_utils.py) contain nearly identical reverse_string functions
• Corresponding test files exist with slight variations in test cases
• Both implementations manually reverse strings without using built-in methods

Proposed Changes:

1. Select the most robust implementation (likely the two-pointer approach from string_reversal.py)
2. Merge test cases from both test files to create a comprehensive test suite
3. Remove redundant implementation
4. Update import statements and references accordingly

Changes Made

1. Consolidated string reversal implementation
2. Merged test cases from both test files
3. Removed redundant module
4. Verified consistent type checking and error handling
5. Maintained existing functionality with manual string reversal

Tests and Verification

1. Executed full test suite for both original implementations
2. Verified all existing test cases pass
3. Confirmed no regressions in functionality
4. Checked error handling for various input types
5. Validated Unicode and special character support
