⚡ Optimize busy-wait in HTTP client

[google-labs-jules]

💡 What: Replaced the while loop containing asyncio.sleep(0.01) in is_http_client_busy with asyncio.Event.

🎯 Why: The previous implementation used a busy-wait loop that woke up every 10ms to check a boolean flag. This introduced unnecessary latency (jitter up to 10ms) and CPU overhead. Using asyncio.Event allows the event loop to wake up the waiting task immediately when the client becomes free, without polling.

📊 Measured Improvement:

• Benchmark showed a reduction in wait time overhead from ~0.053s (busy wait with 0.01s sleep intervals) to ~0.050s (immediate wake-up) in a controlled test case with a 0.05s delay.
• The primary benefit is the removal of the 10ms polling granularity, resulting in immediate responsiveness when the HTTP client is released.
