Description

This PR re-organizes the existing toolbar component, so that we now have V1 (the existing toolbar) and V2 (a placeholder component for the new toolbar), with certain modules shared between the two:

Toolbar/
├── index.ts
├── KnockButton.tsx
├── shared.ts
├── styles.css
├── V1
│   ├── index.ts
│   └── V1.tsx
└── V2
    ├── GuideHoverCard.tsx
    ├── GuideRow.tsx
    ├── GuidesListDisplaySelect.tsx
    ├── helpers.ts
    ├── index.ts
    ├── useInspectGuideClientStore.ts
    └── V2.tsx

Also includes more prep work:

• Adds a toolbar prop to KnockGuideProvider to allow opting into using the new toolbar "v2", while the development continues
• Adds a trackDebugParams prop to KnockGuideProvider and the guide client, so we can turn off reading/writing debug params from the guide client when using the toolbar.
  • This is paving a path toward pulling out the bulk of the debug logic out of the guide client, and moving it to the toolbar modules to tame complexity in the guide client code
• Adds a placeholder component for toolbar v2, that can render based on the knock_guide_toolbar query param and exit out of it.
