RE'd putDisplayed_achievement from ZZ client DLL via Ghidra: the packet sends opcode + 1 zero byte with no achievement ID, acting as a blanket "I saw everything" signal. Server changes: - Track per-character last-displayed levels in new displayed_levels column (migration 0008) - GetAchievement compares current vs displayed levels per entry - DisplayedAchievement snapshots current levels to clear notifications - Repo, service, mock, and 3 new service tests Protbot changes: - New --action achievement: fetches achievements, shows rank-up markers, sends DISPLAYED_ACHIEVEMENT, re-fetches to verify notifications clear - Packet builders for GET/ADD/DISPLAYED_ACHIEVEMENT
