/**
 * Partitions the syntactic members of a type annotation into "internal"
 * (user-writable in this project) and "external" (declared in node_modules
 * or in the TypeScript default lib).
 *
 * Operates on the syntactic AST node, not on a resolved `ts.Type`. Returning
 * the original AST nodes lets callers produce locations, suggestions, or
 * fixes targeting exactly what the user wrote.
 *
 * Classification rules per top-level member:
 * - Keyword / literal types -> internal (the user wrote them directly).
 * - TSTypeReference -> resolves the type name to a symbol and inspects its
 *   declarations.
 * - TSIndexedAccessType with a literal property name -> resolves the accessed
 *   property and inspects its declarations. When no named property matches,
 *   the access goes through an index signature and the signature's own
 *   declaration is used instead (falling back to the declaration of the
 *   indexed type itself for signatures the checker synthesizes, such as
 *   `Record<K, V>`).
 * - Any other composite constructor (TSIntersectionType, TSArrayType,
 *   TSTypeLiteral, TSConditionalType, ...) -> internal at the top level. We
 *   do not recurse; callers can if they need to.
 *
 * A member is external only when ALL of the declarations found for it live in
 * files that satisfy `isSourceFileFromExternalLibrary` or
 * `isSourceFileDefaultLibrary`. Any local declaration (declaration-merging
 * escape hatch) makes the member internal, and so does a member whose
 * declarations cannot be resolved at all — being reportable is the safe
 * default, since callers use this to decide whether a fix is applicable.
 *
 * Known limitations:
 * - Alias chains are not followed. If the user re-aliases an external type
 *   locally (e.g. `type Inner = ReactNode`), the local alias is internal
 *   because the user has a place to edit.
 * - An indexed access with a non-literal index (`Ext[Key]`) is internal: the
 *   property cannot be pinned down syntactically.
 * - A property inherited from an external base is external even though the
 *   local type could redeclare it, because the declaration the user would
 *   have to change is the external one.
