🐛 Allow callFollowingErrorInterceptor when rejecting in ErrorInterceptorHandler

[AlexV525]

Fixes #2462

RequestInterceptorHandler and ResponseInterceptorHandler both expose a callFollowingErrorInterceptor flag in their reject() methods, but ErrorInterceptorHandler.reject() was missing it — it always emits InterceptorResultType.reject, unconditionally skipping any subsequent error interceptors.

The errorInterceptorWrapper in dio_mixin.dart already handles rejectCallFollowing correctly, so only the handler method needed updating.

PR Review: Allow callFollowingErrorInterceptor in ErrorInterceptorHandler.reject

Risk: LOW

Changes Summary

• 3 files changed, +50/-2
• 1 symbol modified (ErrorInterceptorHandler.reject), affecting the error interceptor execution flow
• Fixes QueuedInterceptors strange behavior #2462

Core Verdict

The fix is correct and minimal. ErrorInterceptorHandler.reject was the only one of the three handlers missing the callFollowingErrorInterceptor parameter — both RequestInterceptorHandler.reject and ResponseInterceptorHandler.reject already support it.

The PR description's claim that errorInterceptorWrapper already handles rejectCallFollowing correctly is accurate: in dio_mixin.dart, InterceptorResultType.rejectCallFollowing shares the same branch as next, continuing to subsequent error interceptors. So only the handler method needed updating.

Verification

• dart analyze lib/src/interceptor.dart: no issues
• New test QueuedInterceptor error interceptor reject with callFollowingErrorInterceptor continues: passes
• Full interceptor_test.dart suite (33 tests): all pass
• stacktrace_test.dart: 1 failure (SocketException on request — HandshakeException), confirmed to also fail on main, unrelated to this PR

Findings

1. [suggestion] Test coverage could extend to the non-queued case
   The fix is on the base ErrorInterceptorHandler, so it applies to both InterceptorsWrapper and QueuedInterceptorsWrapper (dio_mixin.dart wraps both via errorInterceptorWrapper). The PR only adds a regression test for QueuedInterceptorsWrapper. A symmetric case for the non-queued InterceptorsWrapper is not strictly required but would make coverage more robust.

2. [ok] Doc comment
   The new dartdoc matches the existing reject doc on the other two handlers exactly. The API shape (optional positional param, default false) is aligned and backwards-compatible.

3. [ok] CHANGELOG
   Entry style matches surrounding entries, placed under the Unreleased section.

Recommendation

APPROVE. The fix is precise, minimal, backwards-compatible, and includes a regression test. Optional improvement: add a symmetric test for the non-queued InterceptorsWrapper case.
