chore: refactor Docker configuration and update exclusion rules

- Add a `.dockerignore` file for Docker configuration
- Ignore git-related files and directories
- Exclude Dockerfile and `.dockerignore`
- Ignore build artifacts including binaries and shared libraries
- Add rules for Go-specific files and directories
- Exclude testing-related files and folders
- Ignore files from IDEs and editors
- Exclude OS-specific and temporary files
- Ignore documentation files and directories
- Add development tools configuration files
- Exclude debug files and directories
