AgentStripView was superseded by WorkConsole during the task-detail
redesign but never wired into any view and never deleted. Drops the
unused Border.agent-strip / diff-meter styles and the 14 agent.* locale
keys that only it referenced, and marks A4 in the feature-unification
spec as resolved by deletion.
List settings were reachable via three doors (header button, context
menu, double-click). Drop the context menu entry, matching the same
cut already made for the "Let Claude handle it" entry point.
