chore(ai): archive gptel and remove it from the live config

I archived gptel to archive/gptel/ since I rarely use it. Moved there: the six gptel modules (ai-config, ai-conversations, ai-conversations-browser, ai-mcp, ai-quick-ask, ai-rewrite), the gptel-tools/ directory, custom/gptel-prompts.el, their test files and utilities, and the four gptel-only specs.

Scrubbed from the live config: the ai-config require in init.el, which also drops the whole C-; a keymap; the gptel-mode emojify hook in font-config.el; the gptel-tools entries in the Makefile clean target and the coverage runner; and the gptel feature notes in README. Cancelled the open gptel tasks in todo.org (the AI Open Work issues, the feature-extension brainstorm, the velox gptel-magit bug).

ai-term stays. It is the ghostel Claude launcher, independent of gptel.

Verified: every module loads, a batch init launch reaches completion clean, and the full test suite shows only pre-existing coverage failures unrelated to this change.

+;;; test-ai-config-gptel-backend-libs.el --- Tests for gptel backend-lib loading -*- lexical-binding: t; -*-
+
+;;; Commentary:
+;; Regression coverage for the "gptel-make-anthropic void" bug.  The local
+;; gptel fork (:load-path "~/code/gptel", :ensure nil) ships no generated
+;; autoloads, so (require 'gptel) alone never loads gptel-anthropic /
+;; gptel-openai where the gptel-make-* constructors live.  The fix is to
+;; require those backend libraries explicitly before constructing backends.
+;;
+;; These tests don't load gptel itself (it isn't reliably loadable in batch);
+;; they stub `require' and the constructors to verify the loader requires both
+;; libs and that `cj/ensure-gptel-backends' calls it before building backends.

+;; gptel defvars these at runtime; declare them here so the wiring test can
+;; let-bind them in a batch session where gptel itself is not loaded.
