ZeroLog

After initialization, ZeroLog allocates no managed objects on the heap, preventing garbage collections, which is crucial for latency-sensitive applications. The README explicitly states it operates in a 'complete zero-allocation manner.'

All formatting and appending occur in a background thread, minimizing work in calling threads and ensuring high throughput. The README emphasizes that 'no formatting occurs in the calling thread.'

Provides both a string interpolation API using C# 10 handlers and a StringBuilder-like API, offering flexibility for different coding styles. Examples in the README snippets demonstrate both approaches.

Supports appending structured data formatted as JSON via AppendKeyValue, enabling better log analysis. The README includes a code snippet showing how to use this feature.
