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.

+;;; Commentary:
+;; Tests for cj/gptel--model-to-string from ai-config.el.
+;;
+;; Pure function that converts a model identifier (string, symbol, or
+;; other type) to a string representation.  Branches on input type:
+;; string (identity), symbol (symbol-name), fallback (format).
