🛑 fix: Stop Agent On Aborted Tool Calls

[lia-by-librechat]

Summary

• Replace the retry-oriented tool error text with an explicit stop-and-wait instruction when LibreChat reports an abort on a cancelled run.
• Keep ordinary failures (including unrelated failures racing a stop) unchanged, and avoid classifying stream-limit or prepared-subagent safety aborts as user stops.
• Apply the same formatting to direct tools, event results, early completions and eager stream completions so model-visible content and step events agree.
• Avoid claiming an in-flight tool had no side effects: its effects must not be assumed.

Checks

• jest --runInBand --coverage=false --silent src/tools/__tests__/toolErrorContent.test.ts src/tools/__tests__/ToolNode.breakerSignal.test.ts src/tools/__tests__/ToolNode.onResultCompletion.test.ts src/__tests__/stream.eagerEventExecution.test.ts (104 passed)
• tsc --noEmit (passed)
• eslint on the 7 changed TypeScript files (passed)
• git diff --check (passed)
