Cache 0.32.6

Cache 0.32.6 fixes authentication when your cache uses a self-hosted Tuist server with a private or internal TLS CA, and tightens the codebase’s Elixir style checks.

• Self-hosted server trust: cache-to-server authorization now respects a custom CA certificate. You can set the new SERVER_CA_CERT_PEM configuration variable so TLS verification succeeds against servers that use private or internal certificate authorities. The cache service’s server connection now uses the same shared CA helper as S3, keeping trust handling in one place.
• Code-quality checks: the Credo check that flags alias, import, and require inside function bodies now also catches those directives inside describe, test, setup, and setup_all blocks. This prevents review-only issues from slipping into test files.
