Fixes issue #498 where an error was logged when Stop() was called on the FTP server. The handleAcceptError method now checks for 'use of closed network connection' errors before logging, preventing unnecessary error logs during normal shutdown. - Move closed connection check before error logging in handleAcceptError - Add test to verify no error is logged during normal server stop Co-authored-by: Florent Clairambault <fclairamb@users.noreply.github.com>
- Fix errcheck issues by explicitly ignoring return values from disconnect() calls - Replace net.DialTimeout with context-aware dialer.DialContext - Replace net.Listen with net.ListenConfig.Listen using context - Fix unused parameter warnings by renaming to underscore - Remove unused nolint directive - Fix variable name length issue (wg -> waitGroup) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
This PR adds a comprehensive test for handling abrupt data connection closure during file transfers to improve error handling coverage.
Changes
TestConnectionClosureDuringTransferwhich tests:Test Coverage
The new test helps ensure that the server properly handles scenarios where the client abruptly closes the data connection mid-transfer, which improves overall code coverage and robustness.
All tests pass locally with race detection enabled and coverage remains at 92.4%.
