Joseph Doherty 0a4e7a822f perf: eliminate per-message allocations in pub/sub hot path and coalesce outbound writes ...

Pub/sub 1:1 (16B) improved from 0.18x to 0.50x, fan-out from 0.18x to 0.44x,
and JetStream durable fetch from 0.13x to 0.64x vs Go. Key changes: replace
.ToArray() copy in SendMessage with pooled buffer handoff, batch multiple small
writes into single WriteAsync via 64KB coalesce buffer in write loop, and remove
profiling Stopwatch instrumentation from ProcessMessage/StreamManager hot paths.
