feat(editor): add Inspector.Node and Inspector.Text

[joaopcm]

Summary

• Add Inspector.Node — render-props component for inspecting selected nodes (styles, attributes, theme defaults)
• Add Inspector.Text — render-props component for inspecting text selections (marks, alignment, link, parent block styles)
• Export both on the Inspector compound component + context types

API

// Full control via render-props
<Inspector.Node>
  {({ nodeType, getStyle, setStyle, getAttr, setAttr, presetColors }) => (
    <div>...</div>
  )}
</Inspector.Node>

<Inspector.Text>
  {({ marks, toggleMark, alignment, setAlignment, linkColor, setLinkColor }) => (
    <div>...</div>
  )}
</Inspector.Text>

// Default rendering (placeholder — wired in next PR)
<Inspector.Node />
<Inspector.Text />

Context

Part of the inspector sidebar redesign (PRODUCT-1739). This is the core API PR — defines the render-props context objects that consumers and pre-built section components will use.

Depends on #3183 (hooks), #3185 (primitives), #3186 (pickers).

Test plan

• pnpm lint:fix passes
• All 119 existing inspector tests still pass
• Types exported for consumer use

Summary by cubic

Add Inspector.Node and Inspector.Text render-props components to inspect and edit the selected node or text. This is the core API for the inspector sidebar redesign (PRODUCT-1739) and enables theme-aware custom inspector UIs.

• New Features
  • Inspector.Node: read/write node styles and attributes, batch style updates, access nodeType/nodePos, theme defaults, and document preset colors.
  • Inspector.Text: read/toggle marks, set alignment, read/write link href/color, and update parent block styles with theme defaults and preset colors.
  • Exported via the Inspector compound (Inspector.Node, Inspector.Text) plus context/prop types.
  • Default rendering is a placeholder; use render-props for now.
