fix: Add topic cache invalidation and auto-creation on metadata requests
Add InvalidateTopicExistsCache method to SeaweedMQHandlerInterface and impl ement cache refresh logic in metadata response handler. When a consumer requests metadata for a topic that doesn't appear in the cache (but was just created by a producer), force a fresh broker check and auto-create the topic if needed with default partitions. This fix attempts to address the consumer stalling issue by: 1. Invalidating stale cache entries before checking broker 2. Automatically creating topics on metadata requests (like Kafka's auto.create.topics.enable=true) 3. Returning topics to consumers more reliably However, testing shows consumers still can't find topics even after creation, suggesting a deeper issue with topic persistence or broker client communication. Added InvalidateTopicExistsCache to mock handler as no-op for testing. Note: Integration testing reveals that consumers get 'topic does not exist' errors even when producers successfully create topics. This suggests the real issue is either: - Topics created by producers aren't visible to broker client queries - Broker client TopicExists() doesn't work correctly - There's a race condition in topic creation/registration Requires further investigation of broker client implementation and SMQ topic persistence logic. |

test: Add comprehensive unit tests for offset/fetch pattern
Add detailed unit tests to verify sequential consumption pattern:
1. TestOffsetCommitFetchPattern: Core test for:
- Consumer reads messages 0-N
- Consumer commits offset N
- Consumer fetches messages starting from N+1
- No message loss or duplication
2. TestOffsetFetchAfterCommit: Tests the critical case where:
- Consumer commits offset 163
- Consumer should fetch offset 164 and get data (not empty)
- This is where consumers currently get stuck
3. TestOffsetPersistencePattern: Verifies:
- Offsets persist correctly across restarts
- Offset recovery works after rebalancing
- Next offset calculation is correct
4. TestOffsetCommitConsistency: Ensures:
- Offset commits are atomic
- No partial updates
5. TestFetchEmptyPartitionHandling: Validates:
- Empty partition behavior
- Consumer doesn't give up on empty fetch
- Retry logic works correctly
6. TestLongPollWithOffsetCommit: Ensures:
- Long-poll duration is NOT reported as throttle
- Verifies fix from commit
