🤖 Augment PR Summary

Summary: This PR adds session-aware sign-in and sign-out controls to the web explorer navigation bar.

Changes:

• Build actions now carry the named authentication view used to render each explorer artifact.
• Explorer pages and HTML error pages pass that view into shared navigation generation.
• Anonymous views display a Sign In link only when an OIDC policy exists.
• OIDC-authenticated views display a POST-backed Sign Out control; machine-key views display neither control.
• The login page continues to be a dedicated provider-selection page without explorer navigation.
• Build-plan view metadata changed from positional indices to stable view-name strings.
• Added an API-key-only E2E sandbox and expanded Hurl/Playwright coverage for public, OIDC, key, and 404 views.
• CI and Makefile targets now execute the new native and containerized authentication-key checks.
• Documentation explains the new non-redirecting, navigation-based OIDC entry and exit behavior.

Technical Notes: Controls are rendered into separately built per-view HTML artifacts, preserving cache and authorization boundaries.
