Move steam_adapter sources from domain.* to modules.* and rename controller package to api. Update package declarations and imports across SteamTestController, SteamPlayerSummaryResponse, SteamClientConfig, and SteamApiService. Update README to re-label Controller -> API layer and Domain -> Business layer and adjust wording about layer boundaries. Also normalize file endings/newlines in several Java files. No functional logic changes were made.
Add project bootstrap for build, CI/CD, and local development. Introduces Maven Wrapper (mvnw, mvnw.cmd, .mvn/wrapper), multi-stage Dockerfile, docker-compose files (compose.yaml, docker-compose.dev.yml), .env, banner and README. Adds Gitea Actions workflow to build, test and push container images. Update application.yml (port -> 8090, virtual threads, API versioning, management/actuator/prometheus settings, Steam API config) and add application-dev.yml for local overrides. Extend pom.xml with caching, observability (actuator, micrometer/prometheus), testing/dev dependencies (testcontainers, devtools, additional spring test modules) to support CI and local testing.
