feat: 词表数据化——AST 提取脚本 + wall.json + 编译器 + boundary/conversation 数据源切换（等价回归全绿）

- scripts/extract_config.py: AST 解析两老项目源码取常量(不 import 源模块),
  生成 seed_profiles/<slug>/{wall.json, brand_values.json, prompts/};幂等可重跑
- app/engine/wall_schema.py: compile_wall(json)→CompiledWall,坏结构/坏 regex
  编译期显性失败(WallConfigError 含字段路径)
- boundary_filter/conversation: 墙词表/话术数据源切换为 DEFAULT_WALL
  (jiancai 出厂 seed),函数逻辑不动、常量名保留为 wall 视图(既有测试零修改);
  wall 数据化新增 pivots/pivots_contact/zero_number/reask_patterns 字段
- 脆锚点迁移: test_inline_prohibitions 断言对象从 conversation.py 源码改为
  wall.json 数据文件,语义等价(唯一允许的测试修改)
- 回归: 322 既有全绿 + 10 新增 wall_schema 测试 = 332;提取脚本两遍无 diff
