Research direction

Start by reproducing the completion request that triggers the TypeScript Server Error in TypeScript 5.7.0-dev.20240912, then trace the reported path from getCompletionsAtPosition through addImportFromExportedSymbol. Done means the same completion no longer produces a Debug Failure; the report does not name a repository file or test.
