Research direction

Start at the gh webhook forward command and inspect how the --secret argument is read and passed to the forwarding request. Add support for GH_WEBHOOK_SECRET, then verify that forwarding still authenticates correctly when the secret comes from the environment and is not required in argv.

Written by the indexing model from the issue text.

Description

When using gh webhook forward --secret <secret>, the secret is passed via the command line arguments (argv). This makes it visible to process listing tools (such as Task Manager on Windows, or ps on Linux) and exposes it to other processes running under the same user.

It would be safer to allow passing the webhook secret via an environment variable (e.g. GH_WEBHOOK_SECRET) so that it doesn't leak into the process list.
