Revert WebSocket transport for browser-wasm dotnettestcli

[Evangelink]

Summary

Reverts #10118 (4ff238798c48501c902a0ae7f3b8458854f522de) to restore the pre-WebSocket dotnettestcli behavior while preserving unrelated commits that landed afterward.

The HTTP transport alternative remains independently reviewed in #10143 and can replace this implementation separately. This PR intentionally contains only the WebSocket revert and does not include the HTTP implementation.

Pull request overview

Restores the named-pipe-only dotnettestcli implementation by cleanly reverting #10118 while leaving the HTTP replacement to #10143.

Changes:

• Removes WebSocket transports, CLI options, authentication redaction, and browser-wasm transport tests.
• Restores named-pipe framing, protocol version 1.4.0, documentation, resources, and API baselines.
• Updates affected unit and acceptance expectations.

🧪 Test quality grade — PR #10149

This PR removes the WebSocket transport layer from the dotnet-test pipe protocol (reverting to named-pipe only). The test changes are almost exclusively deletions of now-obsolete tests and small assertion updates to reflect the reduced protocol version list and property set. Eight modified tests remain to grade; all are well-structured with meaningful assertions.

Grade	Test	Notes
B (80-89)	mod DotnetTestProtocolContractTests. ProtocolVersion_ IsStable	Single equality assertion on the stable protocol string; clean but could add a comment explaining that a mismatch is a wire-protocol break.
B (80-89)	mod ProtocolTests. ProtocolVersion_ IsStable	Single equality assertion on the stable protocol string; mirrors the contract test above — duplication is intentional per the comment, each is individually solid.
A (90-100)	mod DotnetTestPipeBaselineTests. DotnetTestPipe_ TestAppAdvertisesAllSupportedVersions_ NegotiatesDownToV100WithOldSdk	Multiple well-messaged assertions covering handshake presence, version advertisement, negotiation, and attempt number; appropriate integration-test length.
A (90-100)	mod DotnetTestProtocolContractTests. HandshakeMessagePropertyNames_ AreStable	Comprehensive positional equality checks on every stable wire-protocol property; no issues found.
A (90-100)	mod HelpInfoAllExtensionsTests. Info_ WithAllExtensionsRegistered_ OutputFullInfoContent	Exit-code assertion plus full-output wildcard snapshot; appropriate integration-test length; no issues found.
A (90-100)	mod HelpInfoTests. Info_ WhenNoExtensionRegistered_ OutputDefaultInfoContent	Exit-code assertion plus regex snapshot of --info output; appropriate integration-test scope; no issues found.
A (90-100)	mod PlatformCommandLineProviderTests. IsInvalid_ When_Server_ DotnetTestCli_ Without_ DotnetTestPipe	DataRow-parameterized; IsFalse + exact error-message equality; clear AAA; no issues found.
A (90-100)	mod ProtocolTests. HandshakeMessagePropertyNames_ ValuesAreStable	Comprehensive positional equality checks on every stable wire-protocol property; no issues found.
