v0.56.1

TerraVision 0.56.1

• --engine tofu works with OpenTofu 1.13 and later. OpenTofu 1.13 dropped the -v flag TerraVision used to check the engine version, so every run stopped at preflight with Failed to check tofu version. TerraVision now uses -version, which both Terraform and OpenTofu accept. Thanks to @kquinsland01 for the report and the fix (#280).
• Interactive diagrams. The search box now has a label for screen readers.

Diagrams are unchanged.
