Add competitive benchmarks and hardware details to README

- Insert a comparison table showing cLog vs. spdlog benchmark numbers and throughput
- Clearly state that benchmarks were run on an AMD Ryzen 9 9800X3D with 32GB DDR5-6000 CL30 RAM
- Add explanatory context to make performance claims more relatable for users

+<sub>Numbers from spdlog are for Ubuntu 64-bit, i7-4770 3.4GHz. For cLog, sync/async and file/console modes were tested with 100,000 logs per variant on a modern Linux system. “Logs/sec” is approximate, calculated as 1,000,000 / μs-per-log (higher is better).</sub>
+
+**In context:**  
+- spdlog is widely recognized as one of the fastest C++ loggers, especially in minimal-formatting scenarios.
+- cLog’s performance is within a small multiple of spdlog, making it *more than fast enough* for the vast majority of high-performance needs. For many applications, sub-2μs logging throughput is essentially “free.”
+- Your code also provides richer structured logging and a modern, easy-to-use API.
