chore(ci): unblock quality gates - env-doc sync + stryker tap.testFiles registration (#9282) (#11609)

Merged via /merge-batch (lote 2026-08-26 batch 2, v3.8.51). Dois conflitos, ambos triviais: (1) stryker.conf.json — mesma linha com indentação diferente, mantida a indentação correta; (2) ts7-executor-shared-shapes.test.ts — mesma correção já coberta por #11591/#11608 (mergeados neste lote), mantido o describe/comentário melhor deste PR sobre a asserção já validada. Validado: 4/4 testes passando. Obrigado pela contribuição.
