Comprehensive Documentation Update and Naming Standardization

[ppant]

I have performed a comprehensive cleanup and documentation update for the repository. Key changes include:

1. Naming Standardization: Renamed all directories (e.g., deque -> Deque, Error-debug -> ErrorHandling) and many Python scripts (e.g., Anagram_Check_Sorted_Sol.py -> AnagramCheckSortedSol.py) to follow a consistent PascalCase convention.
2. README Overhaul:
   • Updated the root README.md with a structured Table of Contents, improved navigation, and accurate links to all 50 scripts.
   • Standardized all subdirectory README.md files with a "## Contents" section and included time complexity analysis using LaTeX (e.g., $O(n \log n)$) for each implementation.
   • Corrected Shell Sort's worst-case complexity to $O(n^2)$.
3. Refactoring: Updated LinkedLists/SinglyLinkedListCycleCheckImple.py to make cycle_check an idiomatic instance method using self.
4. Verification:
   • Verified that all 49 non-interactive scripts execute successfully with Python 3.
   • Confirmed that all relative links in all Markdown files are valid and point to existing files.
5. Quality Assurance: Addressed code review feedback by removing temporary log files used during the audit process.
