Version 2.5.0 -- breaking change to BufferLogAppender's public constract.

BufferLogAppender now accepts threshold and optional size bounds via its
constructor, replaces bufferMax with the size target/max API, defaults
to bounded buffering, and may reassign its buffer during trim/clear
operations.

Also adds batched buffer trimming for high-throughput logging, a clamp
utility for bounds normalization, and expanded tests for buffer sizing,
trimming behavior, and clamp semantics.
