Arena class

A fallback implementation of the Arena resource pool for web/browser runtimes.

Under environments where FFI/IO is unsupported (such as Web/JS/WASM), this class transparently falls back to using standard heap allocations (StandardDocument.pooled, etc.) rather than native memory page pools. This allows logging code targeting Arena to execute without runtime crashes on all platforms.
