Pull request overview

This PR streamlines configuration and defaults across the repo by (1) adjusting CI workflow triggers/registries and (2) reducing Rust boilerplate by deriving Default for SupervisorPolicy.

Changes:

• Derive Default for SupervisorPolicy using #[default] on the enum variant (removes manual impl).
• Update npm registry configuration to point @trex to the trex Azure Artifacts feed.
• Modify the D2E integration workflow triggers (remove paths filters; add merge_group).
