When a user runs an unknown command that matches a known official
extension (e.g. `gh stack` or `gh aw`), show an install suggestion.
In interactive TTY sessions, prompt the user to install it on the spot.
The official extension registry is hard-coded in pkg/extensions/.
Current entries are github/gh-aw and github/gh-stack. Teams can add
their extensions via PR. Install suggestions use an explicit github.com
host prefix for GHES compatibility.

Detect which AI coding agent is invoking gh by checking well-known
environment variables and include the agent name in the User-Agent
header sent to GitHub APIs.
Supported agents: Codex, Gemini CLI, Copilot CLI, OpenCode,
Claude Code, and Amp. Generic AI_AGENT env var is also supported
with validation to prevent header injection.

This commit expands the in-line docs around updaterEnabled package variable used to affect release checking.
Along with clarifying specific details discovered when talking with @williammartin, I'm also removing a useless local variable.
This commit is a bit of refactoring to bring the extension update checking logic up to par with what is done with `gh` including creation of state file per extension and listening to env vars for disabling version checking.
This work is not complete as it does not address necessary test changes.
