chore: 强化代码质量与风格检查体系

ESLint 升级到 recommended-type-checked + stylistic-type-checked，
引入 perfectionist 导入排序和 import 插件导入验证。

Prettier 显式声明全部格式化参数，消除跨环境差异。
TypeScript 启用 noUnusedLocals 和 noPropertyAccessFromIndexSignature。
完善 ignore 列表，排除 .agents/、bun.lock、data/ 等。
引入 husky + lint-staged（pre-commit）+ commitlint（commit-msg）。
更新 DEVELOPMENT.md 代码质量章节。
修复所有新增规则检测到的类型和风格违规。
