…ve-5m5hv) Removes ChatThreadMinimap entirely — component, its pure derivation (threadMapEvents/toolBarWidth/formatTookLabel), its .cave-thread-map stylesheet rules and its tests — and every UI/preference that could restore it: the Show/Hide activity-map kebab item and the persisted `cave:chat:thread-instruments` preference, which chat now purges from localStorage on mount so a stored opt-out cannot resurrect anything. The left turn spine is retained: ChatThreadSpine mounts again in the transcript's left gutter over the same activePath, component untouched. The Design run rail (ChatActivityMap) is the automatic right-side instrument; the only mount condition left is that a transcript exists. Contract tests are rewritten around the surviving properties, and retired-chat-preferences(.test).ts replaces thread-instruments-visibility with the purge. Closes OpenCoven#4895.
