Summary: Add encoding error tracking to prevent command queue corruption - Add markEncodingError() and hasEncodingError() methods to RedisCommand interface - Implement encoding error flag in Command class with volatile boolean - Mark commands with encoding errors in CommandEncoder on encode failures - Add lazy cleanup of encoding failures in CommandHandler response processing - Update all RedisCommand implementations to support encoding error tracking - Add comprehensive unit tests and integration tests for encoding error handling Fixes issue where encoding failures could corrupt the outstanding command queue by leaving failed commands in the stack without proper cleanup, causing responses to be matched to wrong commands.

Summary
This PR fixes an issue where encoding failures could corrupt the outstanding command queue, causing subsequent responses to be matched to wrong commands and leading to out-of-sync command/response handling.
The issue called out in #2012
Root Cause: When command encoding fails, the failed command remains in the outstanding command stack without proper cleanup, corrupting the command-response matching mechanism.
Solution:
markEncodingError()andhasEncodingError()methodsChanges Made
EncodingErrorHandlingTests) and integration tests (EncodingErrorIntegrationTests,CommandEncodingErrorIntegrationTests)Test Plan
Fixes
This resolves command queue corruption issues that could occur when Redis commands fail during encoding, ensuring proper command-response synchronization is maintained.
