📝 **Task:** Build a small \`dead_letter_handler(msg, retry_count, max_retries)\` that returns one of \`"retry"\`, \`"deadletter"\`, or \`"drop"\`: 1. \`msg.get("malformed", False) is True\` → \`"drop"\` (never retry corrupt input — it'll fail forever). 2. \`retry_count < max_retries\` → \`"retry"\` (still under the budget). 3. \`retry_count == max_retries\` → \`"deadletter"\` (used up the budget — route to DLQ for ops review). 4. \`retry_count > max_retries\` → \`"drop"\` (already DLQ'd; subsequent failures drop silently to stop noise). This pattern is what protects every production queue from poison-message storms. 📋 Implement the function above. Tests run automatically. 💡 **Hint:** Re-read the theory if you get stuck.
