Improves the `version` command to automatically extract build details (version, commit, date) from Go's `debug.ReadBuildInfo` when `ldflags` are not provided. This allows users installing via `go install` to receive accurate version information without requiring a Makefile or explicit build flags. Updates the README to reflect this new capability.
