Godot Navigation and AI

Treat pathfinding, movement, selection, commands, targeting, combat, and local avoidance as separate systems with explicit handoffs.

Inspect the Project First

1. Locate project.godot, read its Godot feature/version tag, and confirm the runtime version when a project-compatible executable is available.
2. Inspect navigation regions, polygons, tile navigation data, links, obstacles, maps, layers, and existing NavigationAgent2D settings.
3. Inspect unit roots, collision shapes, teams, groups/registries, selection UI, input actions, camera transforms, combat APIs, and pause behavior.
4. Search for direct position writes, move_and_slide(), target updates, physics queries, and navigation-server calls. Identify which script currently owns movement.
5. Preserve existing scene inheritance and command interfaces. Prefer CharacterBody2D plus NavigationAgent2D for new colliding units when the inspected project supports that architecture.
