Pull request overview

Adds basic “container” platform support so GDASApp can be built (and potentially run) inside a containerized environment, aligning with Global-Workflow’s container-based compilation approach.

Changes:

• Detect container execution and set MACHINE_ID=container.
• Add container handling to module initialization (module-setup.sh) and to build.sh supported targets.
• Introduce a new Lmod modulefile for GDAS/container.intel.

The Ursa failures are a known problem. g-w PR #4545 will resolve this problem. These failures are not due to the changes in this PR.

GDASApp CI passes on Gaea C6, Hercules, and Ursa - an expected result.

Approve.
