Add first class GitHub Spec Kit support #5415

Describe the feature or problem you'd like to solve

Add first class support for your own Spec Driven Development Framework

Proposed solution

You have so much potential with Spec Kit, exspecially for Enterprise Users that need to persist decisions on why something was implemented. So i could imagine something like another Tab at the top called Spec or SDD, which allows me to initialze speckit directly from the github copilot cli. Then after initialization it shows in that tab a nice dashboard/overview of my current speckit status, like what features were implemented, in which status is the current feature, switching the active feature, adding easily the bug or idea assessment flow. Give me an easy way of taking a look at the created documents and so on. You own all of this already, now just combine it and it will be an amazing ai tool for enterprise users to use.

Example prompts or workflows

• Quality and documented feature implementation
• Bug fixing flows
• Idea assessment flows
