Pull request overview

This PR introduces new path-finding APIs (getPath / getPaths) for navigating factor graphs, refactors older path-related helpers toward those APIs, and adds test coverage for common pathfinding scenarios and filter combinations.

Changes:

• Add getPaths / getPath to the AbstractDFG API surface (as declared services) and implement them using Graphs.jl algorithms in the GraphsDFG backend.
• Deprecate/redirect legacy path utilities (findShortestPathDijkstra, findFactorsBetweenNaive) toward the new APIs.
• Add a dedicated “Path Finding” testset covering shortest path, k-shortest paths, and filtering behavior (labels/solvable/tags).
