Handle planning response parse errors gracefully with retry logic

[yuyutaotao]

Summary

Added error handling for planning response parse errors to allow the task executor to retry planning instead of terminating the entire execution loop. This improves robustness when the AI model returns malformed responses.

Key Changes

• Wrapped the session.appendAndRun() call in a try-catch block to handle planning-phase errors
• Added specific handling for AIResponseParseError exceptions that occur during planning response parsing
• When a parse error occurs, the executor now:
  • Records the error in conversation history as pending feedback
  • Increments the error counter for the current planning loop
  • Triggers a replan attempt instead of failing the entire task
  • Respects maxErrorCountAllowedInOnePlanningLoop to prevent infinite retry loops
  • Respects replanningCycleLimit to prevent excessive replanning cycles
• Non-parse errors are re-thrown to maintain existing error handling behavior

Implementation Details

• Parse errors are distinguished from other errors by checking if the error is an instance of AIResponseParseError
• The error counter and replan count are used to enforce limits and prevent infinite loops
• Error messages are logged for debugging purposes
• When limits are exceeded, an appendErrorPlan() is called with a descriptive error message
• The retry logic uses continue to restart the planning loop, allowing the executor to attempt planning again with the same context
