Important

Add in-memory rate limiter to transition_step with configurable rate limit and update encoding error handling in codec.py.

• Behavior:
  • Add in-memory rate limiter to transition_step in transition_step.py using RateLimiter from utils.py.
  • Raise TooManyRequestsError if rate limit exceeded.
• Configuration:
  • Add transition_requests_per_minute to env.py for rate limit configuration.
• Utils:
  • Implement RateLimiter class in utils.py with acquire() method for rate limiting.
• Codec:
  • Modify to_payload() in codec.py to return FailedEncodingSentinel on encoding failure.
• Tests:
  • Update imports in test_execution_workflow.py for consistency.
