- New deploy/ENVIRONMENTS.md: comprehensive walkthrough of all 4 compose
files with service-by-service explanations, beginner-friendly Docker
concepts, and expert-level networking/config details
- Fix docker-compose.dev.yml: agent LOG_LEVEL → CERTCTL_LOG_LEVEL (was
silently ignored without the CERTCTL_ prefix)
- Add CERTCTL_CONFIG_ENCRYPTION_KEY to base and test compose (enables
M34/M35 dynamic issuer/target config encryption)
- Add CERTCTL_DISCOVERY_DIRS to base compose agent (enables filesystem
certificate discovery in default deployment)
- Cross-link ENVIRONMENTS.md from README doc table and quickstart.md
