Add transactional work queue (dispatcher/performer)#218
Merged
Conversation
Turn AutoControl from "run a script" into "run a robot": a SQLite-backed work queue with per-item status, dedup-by-reference, atomic claim, and REFramework-style retry semantics (application errors retry to max_retries; business errors never retry). Resumable after a crash and parallelizable across performers — the production-RPA pattern that the DAG/scheduler didn't cover. Wired through facade (WorkQueue / WorkItem / BusinessError), AC_queue_add/next/complete/fail/stats executor commands, ac_queue_* MCP tools, Script Builder "Queue" entries, headless tests, and a v10 reference page (EN + Traditional Chinese) + README sections.

Summary
From the round-2 multi-agent research (top pure-stdlib, high-value gap):
turn AutoControl from "run a script" into "run a robot." A SQLite-backed
work queue implements the production-RPA dispatcher/performer pattern
that the DAG/scheduler didn't cover — resumable after a crash,
parallelizable across performers.
