Walkthrough

The project undergoes major structural reorganization: removal of example code, demo modules, CI/CD workflows, containerization setup, and build tooling; refactoring of dependencies; module path rename from github.com/capcom6/go-project-template to github.com/go-core-fx/template; and introduction of a new root-level module.go with FX integration point.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflows .github/workflows/go.yml, .github/workflows/pr-labels.yml, .github/workflows/pr.yml, .github/workflows/release.yml	Disabled benchmark job in go.yml; deleted pr-labels.yml (label stripping automation), pr.yml (PR CI/CD with GoReleaser, S3 upload, Docker publishing), and release.yml (tag-based release workflow). Removes all automated release and PR-comment artifact reporting.
Build & Release Configuration .goreleaser.yaml, Dockerfile.goreleaser, docker.mk, swagger.mk	Removed entire GoReleaser config (builds, archives, Docker images, changelog); deleted multi-stage Alpine Dockerfile; deleted Docker Makefile targets (docker-build, docker-up, docker-down, docker-logs, docker-clean); deleted Swagger documentation generation target.
Development Configuration .air.toml	Removed entire Air configuration including build commands, file filtering, polling, and UI preferences.
Dependency Management go.mod	Renamed module from github.com/capcom6/go-project-template to github.com/go-core-fx/template; removed github.com/go-core-fx/config, github.com/go-core-fx/fiberfx, and direct go.uber.org/zap dependencies; reorganized and trimmed indirect dependencies.
Application Entry Point & Setup main.go, internal/app.go	Deleted main entry point (main.go → internal.Run()) and app bootstrapping logic (internal/app.go → FX app construction with core/app/business modules and lifecycle hooks).
Configuration Module internal/config/config.go, internal/config/module.go	Removed entire config package: deleted config loader (Config, Default(), New()), YAML-based environment loading, and FX module wiring; eliminates dependency on github.com/go-core-fx/config.
Example/Demo Module internal/example/config.go, internal/example/doc.go, internal/example/domain.go, internal/example/errors.go, internal/example/metrics.go, internal/example/models.go, internal/example/module.go, internal/example/repository.go, internal/example/service.go	Deleted entire example module including documentation, domain model (Example), error definitions (ErrExample), Prometheus metrics (Metrics, NewMetrics(), IncTotal()), data models, FX wiring, repository pattern (Repository, Add()), and service layer.
Server Module internal/server/module.go	Removed server FX module setup including named logger configuration and fiberfx.Options provision with JSON error handler and metrics enablement.
New Root Module module.go	Added new root-level FX module with ModuleName constant ("template") and Module() function providing named logger integration; serves as placeholder with commented dependency provider.
