Simplifies the version command and Makefile by removing manual ldflags injection. The application now relies entirely on Go's built-in VCS metadata embedding to extract version, commit, and date information, ensuring accurate reporting across all build methods.
Provides a `gitlocal version` command to display the application's version, commit hash, and build date.
Introduces a `Makefile` to automate builds, installations, and tests. The Makefile dynamically extracts version, commit, and date from git tags, commit hashes, and build timestamps, injecting this metadata into the Go binary via `ldflags`.
Updates the `README.md` to document the new command and recommended build process using the Makefile.
