This reverts commit 6ab1e17.

Build broke - #10029

/home/runner/work/aspire/aspire/src/Aspire.Cli/Backchannel/ExtensionBackchannel.cs(187,27): error IL3050: Using member 'StreamJsonRpc.JsonRpc.Attach(Stream, Object)' which has 'RequiresDynamicCodeAttribute' can break functionality when AOT compiling. This code uses a formatter/serializer that hasn't been hardened to avoid dynamic code.

• Confirm that all references to the removed extension configuration constants (such as ExtensionEndpoint, ExtensionPromptEnabled, etc.) have been updated or eliminated across the codebase.

    public const string CliLocaleOverride = "ASPIRE_CLI_LOCALE_OVERRIDE";

export function isWorkspaceOpen(): boolean {
