`mfer version`, `mfer --version` and the banner print the revision the build stamps into main.Gitrev or, when it stamped none (as after `go install` of a tag), the main module's version from runtime/debug.ReadBuildInfo. The banner no longer shows a release date. mfer.Version and mfer.ReleaseDate go, with main.Version and the version field and parameter in internal/cli that nothing read. A program using the library reads the module version from its own build information. The README says where the version comes from. Judgement call: a binary with no build information, or none holding a module version, prints "unknown", the word script/build already uses when git describe gives nothing. Model: opus-5-5
