John Slaughterrequested to merge
js/flow-builder-integration into main

Description

Description:
This MR integrates the Flow Builder Webview into VS Code, with the goal of creating a "Markdown Preview"-like experience for editing GitLab Flow YAML files.

Key Changes:

  • New Command: Added gl.openFlowBuilder, accessible via the editor title bar when a YAML file is active.
  • Webview Configuration: Configured the Flow Builder to open in the Beside view column and initialized it with the active document's URI via query parameters.
