Debug container workspace paths and retry github.workspace

Add debugging step to show pwd vs GITHUB_WORKSPACE inside container.
Retry using github.workspace - according to GitHub docs it should
work correctly for container jobs as actions run in the container
context with the workspace mounted.

Note: This work was completed with AI assistance (Claude Code).
