Feature request: gh copilot feedback command

[pdebruin]

Problem

There's no built-in way to file feedback or issues from the Copilot CLI. When a user wants to report a problem or suggest an improvement, they have to leave the terminal, find the right repo, and create an issue manually.

Why this matters

The Copilot CLI agent itself assumed gh copilot feedback exists — it suggested it to me as the #1 way to provide feedback. That's a strong signal this command is expected to exist. If the agent hallucinates it, users will too.

gh copilot already has suggest, explain, config, and alias. A feedback subcommand fits naturally.

Suggested behavior

gh copilot feedback

Could:

• Open an issue creation form on github/copilot-cli (like gh issue create --repo github/copilot-cli)
• Or launch a browser to a feedback URL
• Optionally attach session context (CLI version, OS, active plugins) to help triage

Context

Filed from a Copilot CLI session where the agent confidently recommended gh copilot feedback as a command — it doesn't exist. See also #3115 for the issue that prompted this feedback attempt.
