⚡ Bolt: Optimize CodeBlock and ChatThread string generation

💡 What:

• Memoized shown code tokens calculation using manual for loops in CodeBlock.tsx instead of chained .map().join().
• Refactored sig signature generation in ChatThread.tsx to use manual string concatenation rather than allocating a new array and calling .join().

🎯 Why:

• These are hot UI paths in chat polling and rendering. Repeatedly calling .map().join() created unnecessary intermediate array and string allocations, causing CPU and Memory overhead, leading to GC pressure.
• Following .jules/bolt.md performance insights to prevent these overheads.

📊 Impact:

• Reduces memory allocations and Garbage Collection pressure when rendering multiple code blocks and on chat polls.

🔬 Measurement:

• Use React Profiler or performance tools to verify memory usage doesn't spike on active chat polling.
• Unit and UI tests passed successfully.

Closing: micro-optimization of CodeBlock token rebuild (useMemo + manual loops) and ChatThread signature string concat. Same class as #303/#296/#295/#287 — no measurable gain on these UI paths, and it only churns hot rendering code.

Understood. Acknowledging that this work is now obsolete and stopping work on this task.
