All three tests that this PR adds are on main, and they pass in CI there.

• node:stream: sync the stream suite to Node v26.3.0 and fix the gaps it surfaces — stream/iter + zlib/iter behind --experimental-stream-iter, read()-one-buffer semantics, compose/pipeline/web-adapter/http/fs/net parity (247/251 upstream tests, +63 vendored) #31826 added test-stream-pipeline-http2.js. Main has the Node v26.3.0 copy, which adds common.mustCall and common.mustCallAtLeast wrappers to two callbacks.
• net,tls: port Node.js net/tls compatibility tests and fix the gaps they surface — half-open/reset/write semantics, server TLSSocket wrap, session/keylog, SNICallback/ALPNCallback, pfx, OpenSSL error shapes, addCACert, local binding (+305 tests) #31155 added test-tls-wrap-econnreset-pipe.js. The copy on main is identical to the copy here.
• Add support for vm.constants.DONT_CONTEXTIFY #20088 added test-vm-timeout-rethrow.js. The copy on main is identical to the copy here.

This PR adds nothing that main lacks. A maintainer can close it as superseded.
