📝 Walkthrough

Walkthrough

Added a multi-stage Dockerfile for containerization with Maven offline dependency handling and Java runtime entry point. Updated application properties to externalize configuration via environment variables for GitHub OAuth, S3 storage settings, and Hibernate schema management.

Changes

Cohort / File(s)	Summary
Docker Infrastructure Dockerfile	New multi-stage build: Maven offline dependency fetch, skipped compile/tests during build phase, final stage runs JAR with fixed ENTRYPOINT.
Application Configuration src/main/resources/application.properties	Externalized GitHub OAuth credentials and S3 endpoint/region/bucket settings to environment variables; updated Hibernate DDL strategy from create-drop to update; changed S3 provider comment from AWS to Cloudflare R2.

Poem

🐰 A Docker vessel springs to life,
Config flows in without strife!
Secrets dance in env vars' keep,
While schemas update, nice and deep,
From jar to cloud, we leap and bound! 🚀
