[WIP] Fix artifact check to prevent run failure on missing session logs

[Copilot]

• Inspect the failed Copilot Session Insights run and workflow guidance
• Locate the session-artifact fetch and existing validation coverage
• Make missing per-session logs non-fatal while preserving useful reporting
• Recompile the workflow and run focused validation
• Perform security/review validation and publish the final change

• Fixes [aw-failures] Copilot Session Insights: all-or-nothing artifact check fails whole run when any sampled session log is missing #50273

[github-actions]

Thanks for tackling this workflow stability issue @Copilot 👋 — this looks well-focused and directly addresses issue #50273. Here's the current status:

What looks good:

• ✅ Changes are minimal and focused (15 lines across 3 files)
• ✅ Clear mapping to the issue: converts hard-fail error to graceful warning when session artifacts are missing
• ✅ Documentation in the markdown file explains the behavior change well
• ✅ Properly marked as [WIP] with a clear checklist

Before merging:

• This is still in draft—the checklist shows one pending item: "Perform security/review validation and publish the final change."
• Consider adding validation or test coverage for the workflow logic change.
• Once security review is complete and the WIP status is removed, this should be ready for merge.

The change itself is solid—graceful degradation is the right approach here!
