Summary of Changes

This PR adds automated Software Bill of Materials (SBOM) generation for the actor-framework project via a new GitHub Actions workflow. The workflow is scheduled to run weekly (every Saturday at 10:00 UTC) and generates a CycloneDX-formatted SBOM artifact.

The workflow performs the following:

• Resolves the product version from the latest semantic version tag in the repository
• Calls NI's reusable SBOM generation workflow with actor-framework-specific configuration
• Generates a CycloneDX SBOM file at builds/sbom/actor-framework.cdx.json
• Makes the SBOM available as a downloadable artifact named actor-framework-sbom

Reason for Change

Automating SBOM generation aligns with NI's open-source security and compliance standards. Regular SBOM generation provides:

• Consistent tracking of software components and dependencies
• Support for vulnerability management and supply chain security
• Alignment with industry standards (CycloneDX format)
• Automated artifact generation for release documentation

Visual Aids
