What is the new behavior?

Updates the Angular Sanity visual editing implementation for structural and behavioral parity with @sanity/visual-editing v5.4.3.

This PR:

• aligns the Angular-native visual editing runtime with the v5.4.3 upstream folder structure and protocol behavior
• adds Angular counterparts for loader comlink, Presentation queries, visual editing environment state, shared state, telemetry, document reporting, overlays, and optimistic mutation wiring
• bumps the Sanity visual editing runtime dependencies to the v5-compatible major versions
• keeps runtime imports Angular-native and verifies the built app/library do not include React, React DOM, styled-components, or Sanity UI runtime imports
• hardens the Presentation e2e harness so hermetic Studio smoke tests are not affected by local CDP auth settings or dummy Sanity SSR calls

Does this PR introduce a breaking change?

• Yes
• No

The public Angular package peer dependency surface remains compatible. The bumped Sanity packages are implementation dependencies used to match upstream visual editing v5.4.3 behavior.
