build: 移植 PHPCS + PHPStan L6 品質 gate（PR-I 前半）

- phpcs.xml（自 A 移植）：ruleset 改名、*/tools/* 例外換成 */back-compat/*、
  中文註解全域排除 Squiz.Commenting.InlineComment.InvalidEndChar、
  interface 別名檔排除 OneObjectStructurePerFile
- 檔頭正規化：16 個檔案的 declare(strict_types=1) 與前導 // 註解移到
  file docblock 之後，並移除 <?php 後多餘空行（phpcbf 另自動修 190 處）
- phpstan.neon + .phpstan/stubs.php（TMDO_ 與 WPDO_ 兩套常數）+
  重新產生的 phpstan-baseline.neon（710 errors，A 的 3877 行 baseline
  因前綴與路徑不同無法沿用）

現況：PHPCS 0 errors / 0 warnings、PHPStan L6 No errors、
unit 451 / integration 398 GREEN
