enable http2 for js sdk envd rpc/api traffic

[matthewlouisbrockman]

Enables HTTP/2 for JS SDK sandbox envd traffic in Node by routing envd RPC/API requests through undici with an HTTP/2-enabled dispatcher.

Non-Node runtimes continue to use global fetch. Management API and volume clients are unchanged.

Requires bumping node from >=20 to >= 20.18.1 for undici

PR Summary

Medium Risk
Changes the JS SDK’s network transport for sandbox envd RPC/API calls in Node by switching to an undici HTTP/2-capable fetch adapter and raising the minimum Node version, which could affect connectivity/perf and runtime compatibility.

Overview
Enables HTTP/2 for JS SDK sandbox envd RPC/API requests in Node by introducing an undici-backed fetch wrapper (src/envd/http2.ts) and routing both Connect RPC transport and EnvdApiClient requests through it.

Non-Node runtimes continue to use the global fetch. The package now depends on undici, adds unit coverage for the adapter behavior, and bumps the minimum supported Node version to >=20.18.1 (via package.json and a changeset).
