Introduce bst_check_container.m to detect and validate available container runtimes (docker, podman, apptainer, singularity), verify runtime usability (daemon running when required), and ensure a requested container image is available (with optional pull). Returns runtime, original image reference, and local .sif path for Apptainer/Singularity. Includes helper routines for command detection, runtime checks, image existence, and Brainstorm GUI dialogs for user interaction; does not execute containers.
Add an inline comment to toolbox/containers/bst_check_container.m noting the current duneuro container image tag ('ghcr.io/maltehoel/duneuro_in_docker_testing:wip') for testing/developer reference. This is a non-functional documentation-only change.

This PR introduces an initial and experimental interface to explore the use
of containerized external tools from Brainstorm.
Main contributions:
container runtimes (Docker, Podman, Apptainer/Singularity)
This work is intended as a first step and proof-of-concept toward integrating
containers as a supported mechanism to run external tools (eg. duneuro) from
Brainstorm, without requiring users to manually install complex dependencies.
The current implementation is deliberately minimal and meant to enable
discussion, testing, and refinement. In particular, the long-term integration
of container-based tools may be better handled through the Brainstorm Plugin
Manager, rather than via standalone utilities, and this PR is meant to help
inform that design choice.
No existing behavior is modified, and no containers are executed directly
by this current change.
