需求(申晗): worker-budget 不该当 skill(污染 agent 上下文+撑 --help token)， 改成 dashboard 每个 bot 一个「最大活跃会话数」配置项；默认不设上限(资源够用 时老会话永不休眠，体验最佳)，去掉时间超时维度，只按会话数封顶，超过后最久未用 的会话转休眠(下条消息/打开终端唤醒)。 - 删 botmux-worker-budget skill(进 RETIRED_SKILL_NAMES，升级时自动从各 CLI skills 目录清掉) + 删 botmux worker-budget CLI 子命令(含 --help/dispatch) - 删 core/worker-budget.ts(自动推导/idleSuspendMs 全去) + 全局 worker config 块 - BotConfig 加 maxLiveWorkers(per-bot，bots.json)；parseBotConfigsFromText 只认正整数 - idle-worker-sweeper 改纯按数封顶: 无 cap→no-op；超 cap 时按 lastMessageAt 把 最久未用的非 adopt/可恢复后端/非忙(屏幕 idle)会话休眠到 cap 内，无 idle 时间门 (只保留'不打断正在出答案的会话'的正确性守卫)。daemon 每分钟读实时 bot.config 免重启生效 - bot-config-store 新增 'number' 字段 kind(coerce 校验正整数) + 注册 maxLiveWorkers - dashboard: 群组与机器人卡片加「会话数上限」section + /api/bots(/:appId)/ max-live-workers PUT 通道(经 applyConfigField 落盘+内存热更) + zh/en i18n - 测试: 重写 idle-worker-sweeper(8 例，覆盖无 cap/纯计数无时间门/pty/忙/adopt) + bot-config-store number kind + bot-registry parse + builtin-skills 退役断言; 删 worker-budget*/global-config-worker 测试

背景
申晗指出
botmux-worker-budget不该当 skill——既污染每个 agent 会话的上下文（描述常驻），非 skill 注入的 CLI（如 GPT）还会靠--help读到它撑大 token。需求收窄为：底层「超阈值→暂停最久未用 worker→下条消息 forkWorker 唤醒」机制本就存在（idle-worker-sweeper），本 PR 是把它从全局自动预算改成 per-bot 纯计数封顶，并把入口从 skill/CLI 挪到 dashboard。
改动
botmux-worker-budget移出BUILTIN_SKILLS，加进RETIRED_SKILL_NAMES→ installer 下次 spawn 时自动从各 CLI skills 目录清掉旧目录。botmux worker-budget子命令（jsdoc/help/实现/dispatch 全删）→ 减--helptoken。core/worker-budget.ts（CPU×2/内存推导、idleSuspendMs、30min 门）+ 全局workerconfig 块。默认 = 无上限。BotConfig.maxLiveWorkers（写 bots.json，parseBotConfigsFromText只认正整数，≤0/小数/非数→undefined=不限）。lastMessageAt把最久未用的 非 adopt + 可恢复后端(tmux/herdr/zellij) + 非忙(屏幕 idle) 会话休眠到 cap 内。无 idle 时间门——只保留「不打断正在出答案的会话」这个正确性守卫；若超额会话恰好都在忙，本轮不动等下轮。daemon 每分钟读实时bot.config.maxLiveWorkers，dashboard 改完免重启 60s 内生效。PUT /api/bots/:appId/max-live-workers→ 经applyConfigField（新增'number'字段 kind，coerce 校验正整数）落盘 + 内存热更；zh/en i18n。物理事实（已在 UI 帮助文案中说明）
测试
idle-worker-sweeper.test.ts（8 例：无 cap/无 idle 时间门的纯计数/pty 不暂停/忙时不暂停/adopt 守卫）。bot-config-store.test.ts加'number'kind round-trip + coerce 校验；bot-registry.test.ts加maxLiveWorkers解析；builtin-skills.test.ts改成退役断言。worker-budget*/global-config-worker测试。pnpm build0 error；全量单测 4524 passed。未发版、未部署。
