Fix export symbol highlighting in both Dazzle themes

[Copilot]

Export symbols were not being highlighted consistently with the theme's color scheme. In the original issue, export default keywords were correctly highlighted in yellow/red, but the exported identifier (AuxmodoHome) remained unstyled (white/default color).

Before

After

Changes Made

• Added comprehensive token color rules for exported identifiers in both dark and light themes
• Exported symbols (variables, functions, classes) now use the blue entity color:
  • Dark theme: #34b3de
  • Light theme: #00acd7
• Added support for various export-related token scopes:
  • meta.export variable.other.readwrite
  • meta.export entity.name.function
  • meta.export entity.name.class
  • meta.export entity.name.type
  • variable.other.readwrite.alias
  • entity.name.function.export
  • entity.name.class.export
  • variable.language.default.export

Example

export default AuxmodoHome;           // "AuxmodoHome" now highlighted in blue
export const namedExport = "test";    // "namedExport" now highlighted in blue
export function exportedFunction() {} // "exportedFunction" now highlighted in blue
export class ExportedClass {}         // "ExportedClass" now highlighted in blue

The exported identifiers now properly match the theme's entity color scheme, making the code more visually consistent and easier to read.

Fixes #2.
