The completion system was crashing when trying to get completion entry details for JSDoc @import statements. Consider:

/** @import * as t from './types.ts' */

import { preventDefault } from "./other-file.js";

p // <-- requesting completions here would crash

The error was:

Debug Failure. Invalid cast. The supplied value [object Object] did not pass the test 'isTypeKeywordToken'.

Root Cause:
The completion system tries to promote type-only imports to regular imports when they are used in value contexts. For JSDoc @import statements, this promotion logic incorrectly assumed the import had a type keyword that could be found and removed, but JSDoc imports don't have this structure - they are inherently type-only.

Solution:
Added a check in promoteImportClause function to skip type keyword deletion for JSDoc imports:

function promoteImportClause(importClause: ImportClause) {
    // JSDoc imports are inherently type-only and don't have a removable 'type' keyword
    if (!isJSDocImportTag(importClause.parent)) {
        changes.delete(sourceFile, getTypeKeywordOfTypeOnlyImport(importClause, sourceFile));
    }
    // ... rest of function
}

This allows JSDoc imports to be safely handled during the completion promotion process without attempting to remove a non-existent type keyword.

Fixes #62027.
