Full changelog

46abdc9: Re-enable the HTTP/2 (s2s) transport on Bun >= 1.3.11, where Bun's node:http2 connection-level flow control is fixed (oven-sh/bun#26917). Older Bun versions keep the fetch transport fallback.
5cba2c2: Enable the HTTP/2 (s2s) transport on Deno >= 2.7.5. Buffers response body chunks until headers arrive, working around Deno's node:http2 emitting data before response; older Deno versions keep the fetch transport fallback.
51e38a7: Pool HTTP/2 connections in the s2s transport: all streams targeting the same endpoint now share one connection, opened lazily on the first request, instead of one connection per S2Stream handle. Each connection carries up to 100 concurrent requests; beyond that, additional connections are opened. Connections are closed when the last stream handle using the endpoint is closed.
