:copilot: gh agent-task now works on ghe.com tenancies

gh agent-task commands previously failed with 401 Unauthorized for users on ghe.com tenancy hosts because the Copilot API URL was hardcoded. The URL is now resolved dynamically per host, so gh agent-task works correctly regardless of your GitHub hosting environment.

Experimental new prompter

A new TUI-based prompter powered by charmbracelet/huh is available behind the GH_EXPERIMENTAL_PROMPTER environment variable. This is an early preview — try it out and share feedback!

export GH_EXPERIMENTAL_PROMPTER=1

gh issue create and gh issue transfer no longer require extra token scopes

gh issue create and gh issue transfer previously fetched repository fields they didn't need, which could require additional token scopes. These commands now fetch only the minimal fields necessary for issue operations.
