No way to list group/supergroup members

[kfastov]

Problem

groups members only has add and remove subcommands. There's no way to list current members of a group or supergroup.

Repro

tgcli groups members --help
# → Commands: add, remove
# No "list" command

Use case

For group analytics (sentiment analysis, project discovery, user profiling), knowing who the participants are is essential. Telegram API supports channels.getParticipants for this.

Expected

tgcli groups members list --chat <group-id> [--limit N] [--json]
# → list of members with id, username, displayName, role (admin/member/etc)
