fix(ai-term): keep agent buffers alive through the kill-all sweep

F1 (cj/dashboard-only) kills every other buffer, burying only those on the undead list. Agent buffers were never registered, so the sweep killed live agents and detached their sessions.

Agent buffers are a dynamic family ("agent [<project>]") that an exact-name list can't pre-enumerate, so undead-buffers gains a regexp list (cj/undead-buffer-regexps) and a centralized cj/--buffer-undead-p predicate. Both kill paths route through it. ai-term registers the "agent [" pattern, so every agent -- current or future, however created -- is buried rather than killed.
