feat(ai-term): step into detached sessions too, attaching them

The next-agent step (C-; a n / M-SPC) cycled only live agent buffers, so a detached session (alive in tmux, no Emacs buffer) was reachable only through the picker. Now the queue is every active agent, live buffer or live session, keyed on the project dir and ordered by buffer name. Stepping onto a detached one attaches it: show-or-create recreates the terminal, which reattaches the tmux session. The live-buffer swap path is unchanged. I replaced the buffer-rotation helper with a dir-based one and added an active-agent enumerator, with 10 tests.

-;;; Commentary:
-;; The pure decision helper behind `cj/ai-term-next' (s-F9).  Given the
-;; current agent buffer and the ordered list of live agent buffers, it
-;; returns the next buffer in the queue, wrapping after the last.  A nil
-;; or non-member CURRENT returns the first; an empty list returns nil.
-;; No buffer or window side effects -- list logic only.
