refactor: clean up duplicate algorithm implementations to reduce maintenance overhead (#7256)

refactor: remove duplicate algorithm implementations Removed the following duplicate implementations: - searches/PerfectBinarySearch.java (duplicate of IterativeBinarySearch) - searches/SortOrderAgnosticBinarySearch.java (duplicate of OrderAgnosticBinarySearch) - strings/LongestPalindromicSubstring.java (duplicate of dynamicprogramming version) - strings/ValidParentheses.java (duplicate of stacks version) - others/cn/HammingDistance.java (duplicate - strings version handles text) - others/NewManShanksPrimeTest.java (orphan test in wrong package) Updated DIRECTORY.md to reflect the changes. Fixes #7253 Co-authored-by: Ahmed Allam <60698204+AllamF5J@users.noreply.github.com>
