§15 Runaway Guard — per-task dispatch_count 上限，防止无限循环 dispatch 问题：mail/toolchain task 走 handler auto-working（跳过 claim），不受 claim_timeout 3 次重试兜底保护。如果反复 spawn 但永远到不了 done/failed， 会无限循环消耗资源（实际案例：2026-06-15 mention 重复投递事件）。 设计： - tasks 表新增 dispatch_count 字段 - 每次 ticker 成功 dispatch 时递增 - dispatch_count >= 10 时自动标 failed（reason=runaway_guard） - 覆盖所有非终态（pending/working/claimed） - 参考 Hermes v0.13 §3 Per-Task 重试上限 改动文件： - src/blackboard/db.py: _safe_add_column dispatch_count - src/blackboard/models.py: Task dataclass 加 dispatch_count - src/daemon/ticker.py: dispatch 递增 + _check_timeouts runaway guard - docs/design/15-runaway-guard.md: 设计文档 - tests/integration/test_ticker_integration.py: E13 测试 3 个 测试：456 passed, 3 skipped
