Patch Changes

• #10243 96c630d Thanks @hntrl! - fix: add explicit : symbol type annotations to Symbol.for() declarations for cross-version compatibility

  TypeScript infers unique symbol type when Symbol.for() is used without an explicit type annotation, causing type incompatibility when multiple versions of the same package are present in a dependency tree. By adding explicit : symbol annotations, all declarations now use the general symbol type, making them compatible across versions while maintaining identical runtime behavior.

  Changes:

  • Added : symbol to MESSAGE_SYMBOL in messages/base.ts
  • Added : symbol to MIDDLEWARE_BRAND in agents/middleware/types.ts (also changed from Symbol() to Symbol.for() for cross-realm compatibility)
