Subject: [PATCH] fix: add --version flag and correct ldflags module path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add --version flag to CLI (closes bd-bxt)
- Fix ldflags module path: csv2excel/internal/version → code.beautifulmachines.dev/jakoubek/csv2excel/internal/version
  so build info (version, commit, date) is actually embedded into the binary
- Add mg.Deps(Build) to Install so it always builds before installing
