Summary of Changes

Hello @kooksee, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modernizes the project's dependency management by updating the Go version and various libraries, including a significant shift in error handling practices. It also refactors the OpenAPI documentation generation and serving infrastructure, moving UI-related configuration and routing to a dedicated templates package for clearer separation of concerns. These changes aim to improve maintainability, leverage newer Go features, and streamline the project's architecture.

Highlights

• Go Version and Dependency Updates: The Go version in go.mod has been upgraded from 1.20 to 1.23. Key dependencies like kin-openapi were updated, goccy/go-json and github.com/pubgo/funk were removed, and github.com/samber/lo was introduced, leading to a significant cleanup of indirect dependencies in go.sum.
• Refactoring of OpenAPI Configuration and Routing: The Config struct and related routing logic (InitRouter, OpenapiDataHandler) were moved from the opendoc package to a new templates package. The Swagger struct in opendoc now directly manages its Title, Description, and Version fields, simplifying its structure.
• Improved Error Handling: The github.com/pubgo/funk/assert library has been replaced with standard log.Panic or slog.Error for critical errors and github.com/samber/lo for 'must' operations, leading to more idiomatic Go error handling.
• New Build and Example Targets: A Makefile was added, introducing vet for static analysis and run-example for easily executing the example application. A .version file was also added, setting the project version to v0.1.1.
• Enhanced Security Provider Typing: The security package now uses a new AuthProviderType enum for defining security scheme providers, replacing simple strings for better type safety and clarity.
• Added Tag Management: New AddTags methods were introduced to both opendoc/Operation and opendoc/Service structs, allowing for better organization and categorization of API endpoints.
