[BUG] `/workflows` command not available in VS Code extension

What's Wrong?

The /workflows slash command is not available in the Claude Code VS Code extension. Typing /workflows in the extension's input does not autocomplete or execute (see screenshot), even though dynamic workflows are documented as generally available in the VS Code extension.

What Should Happen?

/workflows should list running and completed workflows, as it does in the CLI, since dynamic workflows are documented as GA in the VS Code extension.
