fix: detect v1 client abort explicitly

[c121914yu]

Summary

• add a dedicated client abort tracker for v1 workflow dispatch
• pass the v1 API request into workflow dispatch so abort detection can use request/socket events
• cover normal response close vs premature client abort cases in workflow dispatch tests

Tests

• pnpm --filter @fastgpt/service test test/core/workflow/dispatch/index.test.ts

[Copilot]

Pull request overview

This PR improves v1 workflow dispatch client-abort detection by introducing a dedicated abort tracker that uses request/socket/response signals, wiring the v1 API request object into dispatchWorkFlow, and adding targeted tests to distinguish normal response closure from premature client disconnects.

Changes:

• Add createClientAbortTracker utility to robustly detect premature client disconnects (req/res + socket events, snapshot checks).
• Pass req into dispatchWorkFlow for v1 dispatch paths so abort detection can observe request/socket lifecycle.
• Add unit tests covering “close after finished” vs “close before finished” and socket-close scenarios.
