【策划架构】Lua拓扑排序：祖玛教主上线脚本的依赖排程

for i = 1, #SCRIPTS do
    run(SCRIPTS[i])                  -- 按文件序盲跑，依赖未就绪
end

local DEG, SUCC = {}, {}
local function depend(a, b)          -- a 依赖 b
    SUCC[b] = SUCC[b] or {}
    SUCC[b][#SUCC[b] + 1] = a
    DEG[a] = (DEG[a] or 0) + 1
end
depend("drop_zuma", "core_items")    -- 祖玛教主爆率依赖物品库
local q, i = {"core_items"}, 1
while i <= #q do
    local cur = q[i]; i = i + 1
    sendmsg(actor, 1, "上线 " .. cur)
    for _, nxt in ipairs(SUCC[cur] or {}) do
        DEG[nxt] = DEG[nxt] - 1
        if DEG[nxt] == 0 then q[#q + 1] = nxt end
    end
