feat(toolbox): F1 拆书 teardown 落库成项目 rules

- teardown_spec.writes=["rules"]（只声明 tier，入库仍经白名单 gate，不变量 #3）
- toolbox_registry teardown entry 加 ingest=IngestSpec(table="rules")
- routers/toolbox.py 通用 ingest dispatcher 加 _ingest_rules：
  BookTeardownResult(themes/archetypes/structure/hooks) 拍平为可读 rules 条目，
  落项目级（无 continuity 预检，仿 _ingest_outline 无 409）
- schemas/toolbox.py 加 TeardownIngestView + ToolIngestRequest.teardown
- 单测：teardown ingest→rules 真落行 + 预览(generate)不写库
