feat(telega): add telega.el module with docker-backed TDLib

New `modules/telega-config.el` configures telega.el as an in-Emacs Telegram client. `telega-use-docker' is on so TDLib runs in a container instead of needing a system-level build -- pairs with a follow-up `scripts/setup-telega.sh' for fresh-clone installs. First-run auth (phone + verification code) is interactive inside `M-x telega' and isn't scripted here.

Launcher binding: `C-; G` (mnemonic: teleGram). `C-; t` and `C-; m t` were both taken (test-runner, music's "repeat track"), so the launcher landed on a free top-level letter.

Two tests cover the wiring: module loads, launcher is bound.

+;;; test-telega-config.el --- Tests for Telegram (telega) module wiring -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Lightweight asserts that the module loads, exposes the launcher,
+;; sets the docker preference, and registers the C-; G keybinding.
+;; The bulk of telega.el's behaviour is owned upstream; the tests
+;; here only cover what this config wires.
+
+;;; Code:
+
+(require 'ert)

+(add-to-list 'load-path (expand-file-name "modules" user-emacs-directory))
+(require 'telega-config)
+
+(ert-deftest test-telega-config-loads-cleanly ()
