feat: distribution package v1.0 — OCIR-based deployment without source code

- distribution/: public release package (docker-compose + terraform VM + README v1.0)
- docker-compose.yml pulls pre-built images from OCIR (no build, no source code)
- terraform/: VM stack (ARM Free Tier, LB+WAF+SSL, conditional DNS/Let's Encrypt)
- Removed terraform-oke/ and k8s/ from git (private, .gitignore)
