Implements algorithm ideas from reviewed open PRs, rewritten to match the repo's code standards (type hints, docstrings, complexity notes): - backtracking: minimax with alpha-beta pruning - bit_manipulation: Gray code generation and conversion - data_structures: KD-tree with nearest-neighbor search - dynamic_programming: bitmask TSP, grid path counting (3 approaches) - graph: Edmonds' blossom algorithm for maximum matching - math: linear regression (OLS + R² + RMSE), Manhattan distance, polynomial long division - searching: exponential search, sentinel search - string: alphabet board path, Manacher's palindrome, swap characters, Z-algorithm pattern matching Includes 70 new tests (485 total) and README entries for all additions.
