Profile "local" points Steam, Twitch/IGDB and speedrun.com to a WireMock
container from compose.yaml (recordings in local/wiremock) and checks
logins against the local Auth.
The IGDB lookups now keep only the ids they asked for: an answer with
another game made tags and release years drop the whole batch.
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.
