ChatSettingsStore keeps each chat's IANA zone in <AgentDir>/telegram/chat-settings.json; ChatTimeZoneService is the one path for a change (store, live session, scheduler re-evaluation, reply text). ChatRegistry.TimeZoneFor now reads the store and new sessions start in the chat's zone. /timezone, the set_timezone tool (ChatSettingsExtension), /status zone line, DEFAULT_TIMEZONE. The store updates its cache under the write gate so the last file written is the newest state.
