fix(ai): register execute_sql tool in Electron tool registry

sqlQueryTool (execute_sql) was listed in BUILTIN_TOOL_CATALOG and
available in the CLI AGENT_TOOL_REGISTRY, but was never imported or
registered in the Electron-specific TOOL_REGISTRY. Users who enabled
the tool via the assistant config panel would trigger a missing-tool
error at inference time.

Add sqlQueryTool to the Electron registry following the same
adaptSharedTool pattern used by all other analysis tools. Add a
catalog/registry drift guard test (name + category) covering all
BUILTIN_TOOL_CATALOG entries, enabled via
--experimental-test-module-mocks to mock Electron runtime deps.
Document the general-over-specific assertion rule in AGENTS.md.

 - 必须加测试：修复 bug 时必须先加能失败的回归测试；修改数据库 schema/迁移、导入解析、去重逻辑、权限认证、AI 工具 allowlist、配置/API key 迁移、跨端共享 service 时必须加或更新测试
 - 可以不加测试：只改文案、样式、类型声明、日志、注释、无行为变化的小重构时，可以不新增测试，但仍需运行相关类型检查、lint 和 format
 - 测试分层：纯函数、解析/格式化、权限判断、参数规范化、错误分支优先写单元测试；SQL 行为、数据库迁移、文件迁移、导入写库、Fastify route、跨包 service 优先写集成测试；Electron、真实浏览器、真实 LLM、真实网络仅用于少量关键 E2E/Smoke，并默认通过环境变量显式启用
-- 避免重复测试：新增测试前先搜索同类断言；如果下层单测已覆盖算法，上层只测调用链是否接通，不重复枚举算法细节；如果测试只锁定实现写法、失败后不指向用户可见风险，应合并、改写或删除
+- 避免重复测试：新增测试前先搜索同类断言；如果下层单测已覆盖算法，上层只测调用链是否接通，不重复枚举算法细节；如果测试只锁定实现写法、失败后不指向用户可见风险，应合并、改写或删除；优先写能覆盖全量场景的通用断言，而非针对单个条目的专项断言——若通用断言已完整覆盖，单个断言是冗余的
 - 测试替身选择：涉及 SQL、数据库迁移、Fastify route 或跨包 service 时，优先使用轻量内存 SQLite / 临时文件 fixture 验证真实行为；只有在测试纯适配边界时才使用 mock/fake。避免用大量 `sql.includes(...)` 一类字符串匹配来模拟数据库行为
 - 适配层测试边界：CLI/Electron/Web route、IPC adapter、tool adapter 只验证参数传递、权限过滤、错误映射和返回契约；core 已覆盖的算法矩阵不要在入口层重复展开
