refactor(signal): retire the in-Emacs signel client to the archive

Agents drive Signal via signal-cli and signal-mcp, so the interactive client earns no keep. I moved signal-config.el and its seven test files to archive/ per the pasture convention, dropped the require from init.el, removed the dashboard's Signal launcher (row sizes now 5 4 3 2, tests updated), and unregistered the C-; M prefix from the running daemon. The ~/code/signel fork repo is untouched. The spec record stays IMPLEMENTED with a retirement history line, and the messenger-unification draft carries a premise-shift note.

-;;; test-signal-config--contact-cache.el --- Contact-cache lifecycle tests -*- lexical-binding: t; -*-
-
-;;; Commentary:
-;; The picker's contact cache has two lifecycle bugs from the 2026-06 config
-;; audit: (1) its docstring promised clearing on signel-stop but nothing
-;; cleared it, so a stale list survived a relink/reconnect; (2) a
-;; fetched-and-empty list was cached as nil, indistinguishable from a cold
-;; cache, so a zero-contact account re-ran the blocking fetch (up to
-;; `cj/signel-fetch-timeout') on every picker open.  The fix names the empty
-;; state with an `empty' sentinel and clears the cache via a named function
-;; advised onto `signel-stop'.
-;;
-;; Boundary mocks only (the RPC send, the prompt); the cache logic runs
-;; real.  The ensure-started branches the audit called untested were
-;; already covered in test-signal-config.el -- that claim was stale.
