host d51c06a900 Worker concurrency (capacity enforced), survival (heartbeat/sweep/drain), retry endpoint 
1. Concurrency: capacity is now a real limit, not display-only.
   run_all with capacity>1 runs a manual thread pool (threading,
   not concurrent.futures: a test in this repo puts cloud/ on
   sys.path, shadowing stdlib queue and breaking
   concurrent.futures' SimpleQueue import). Claim stays CAS, so
   two threads racing one task still yield one owner; max_tasks
   counts dispatched+running to avoid overshoot; stop signals
   stop new claims only, running tasks are drained by run_loop.
   Running state moved from single fields to a _running dict
   (proc/container per task) so cancel kills the right task.
   Docker timeout is now a per-call argument, never a mutated
   shared executor field. CostStore opens a fresh connection per
   record/report (shared sqlite connection is thread-bound and
   raised ProgrammingError under the pool; :memory: keeps the
   shared connection because a fresh one is an empty DB).
   Final status write is CAS on status='running' so a background
   thread cannot overwrite an interrupted task with completed.
2. Survival: run_loop starts a daemon heartbeat thread (every
   30s, refreshes running tasks' last_heartbeat) and sweeps stale
   tasks every round (threshold 300s, best-effort); live tasks
   never go stale now, dead workers' tasks are reclaimed without
   manual /admin/sweep. On exit, run_loop waits up to
   drain_timeout (CLI --drain-timeout, default 60s, inside
   systemd's 90s stop window) for running tasks before killing
   leftovers and marking interrupted.
3. Retry: POST /tasks/{id}/retry (maintainer+, 404/403/409):
   failed/interrupted/merge-failed go back to queued with
   result/error/model cleared, prompt/model/deps kept, CAS
   update, audit task_retried.
Tests: 5 concurrency tests (barrier overlap, serial capacity=1,
max_tasks, wait_for_running, CAS final write), 3 retry tests;
full suites pass.

"""云端控制面 HTTP server（首版）。
零第三方依赖，只用 http.server + sqlite3 + 标准库。
分工与边界（以实际代码为准，不夸大）：
- 本 server 只做控制面：项目/任务的创建、查询、取消、心跳、
stale 任务回收，以及 GitHub/Slack webhook 的验签与解析。
- 本版不直接跑模型回合。任务状态机与 host.py 对齐：
queued -> running -> completed/failed/interrupted/merged/merge-failed，
其中 completed/merged 由 worker/控制面后续调用方更新（例如 worker
调 host.py 跑完回合后回写），本 server 不提供“跑模型”端点。
- 其它已就绪模块（queue 的 order_tasks/ready_tasks、sandbox 的执行器、
memory 的 MemoryStore、kb 的 KBStore、models 的 ModelRouter、
cost 的 CostStore、webhooks 的 NotificationService）本版尚未接成
HTTP 端点，留给 worker 接线时调用；本 server 只接入其中两处：
AuthStore（认证/权限/审计）与 webhooks 的验签/解析函数。
- DockerExecutor 已接通（见 sandbox.py），CloudExecutor 目前仍是占位
（见 sandbox.py），本 server 不假装已接通云端执行。
导入规则：只用绝对包导入（from cloud.auth import ...）。绝不要把
cloud/ 目录加进 sys.path：标准库已有 queue 模块，会和 cloud/queue.py
撞名，导致 stdlib queue 被错误模块覆盖。
状态库：单一 SQLite 文件。AuthStore 用 users/project_members/
audit_log 三张表；本 server 用 projects/tasks 两张表，表名不冲突。
并发：ThreadingHTTPServer 多线程处理请求，每个请求内新建 SQLite
连接（server 表用新连接，AuthStore 每次请求新建一个实例），绝不在
多线程 handler 间共用一个连接。
启动：
python3 -m cloud.server [--host 127.0.0.1] [--port 8765] [--db <路径>]
后端由 CLOUD_DB_BACKEND 选（sqlite 默认；postgres 已接通，
驱动缺失时启动即明确报错，见 cloud/db.py）。
测试用 create_server(db_path, host, port) 只返回 ThreadingHTTPServer
实例，不自动 serve。
