Bloch Sphere Widget - Command and Dev Playground

[ScottCarda-MS]

Bloch Sphere View for Q# UX (Playground + VS Code)

Summary

This PR introduces an interactive Bloch sphere view in the shared Q# UX package and wires it into both:

• the dev playground (as a first-class Tools view)
• the VS Code extension webview (via a dedicated command)

It also adds the synthesis data/tooling used by the Bloch Rz helper.

What’s Included

New Bloch UX surface

• Adds a new Bloch widget implementation in the shared UX layer.
• Includes gate application controls, sequence playback/history, and Rz synthesis integration.
• Includes theme-aware rendering/styling for host environments.

Shared math and compute cleanup

• Introduces shared quantum math primitives used across Bloch/state visualization paths.
• Refactors relevant state-viz worker computation to align with shared math utilities.

Rz synthesis artifacts and generator source

• Adds checked-in lookup artifacts:
  • source/npm/qsharp/rz-array.json
  • source/npm/qsharp/rz-details.json
• Adds generator source/tooling for reproducibility:
  • source/npm/qsharp/tools/rz-synthesis.ts
  • source/npm/qsharp/tools/tsconfig.json

Playground integration

• Adds Bloch view routing/rendering in the dev playground.
• Adds navigation entry placement under Tools.

VS Code integration

• Adds/updates webview command plumbing for Bloch panel display.
• Ensures webview/learning webview type-check configs support shared UX JSON import path.

Packaging and dependency updates

• Updates npm dependency metadata and lockfiles.
• Updates component governance manifest for shipped dependency compliance.

Are the colors we want in dark mode? I find the arrows and the axis labels pretty close together.

Edit: from the code, they seem to have been chosen pretty deliberately. I find the white on beige a little strange, but it's not substantially hurting readability.

Also, this might just be my ignorance, but is n/a the appropriate value for phi here?

[amcasey]

Were we expecting it to expand with the pane?

It seems like the slider at the bottom manipulates Rz in radians but the angles at the top are in degrees? Maybe that's a feature?

[amcasey]

Personally, I'd find it very helpful to see the ending state in the top-level summary (maybe top-right) and not just in the sidebar.

[amcasey]

Is the Reset button supposed to clear the Rz slider too?

Random drive-by comments. That's a lot of 3D geometry code to review...
