⚡ Bolt: Regex token extraction optimization

[DerUntote]

💡 What: Replaced .trim().split(' ').filter(...) with .match(/\S+/g) || [] across all message parsing logic.
🎯 Why: The original approach iterated through the string multiple times and allocated unnecessary intermediate arrays. The Regex approach achieves identical logic in a single pass without extra memory allocation.
📊 Impact: Reduced memory overhead and intermediate array allocations during token extraction.
🔬 Measurement: Verify message extraction functionality remains identical, especially handling cases with multiple spaces. Ensure || [] provides safe fallbacks for blank inputs.
