🎯 What: The testing gap for AStar.cs was addressed by adding MSTest unit tests covering behavior requirements.
📊 Coverage: Scenarios covered include basic shortest paths, edge weights favoring, disconnected nodes, missing start/end nodes, directed vs. undirected traversal, invalid argument exceptions, and a more complex 2D spatial grid.
Result: Line coverage for AStar.cs has reached 97.8%, up from 0%. A bug causing a StackOverflow due to cyclic undirected edge additions was also discovered during testing and fixed.

- Implemented comprehensive unit tests for AStar pathfinding algorithm
- Tested directed, undirected, disconnected, missing nodes, null heuristics, and grid paths
- Fixed StackOverflowException caused by infinite recursion for undirected edges by ensuring mirrored edges specify IsDirected = true.
- Brought AStar line coverage up to 97.8%
