Stamp the git tag or short commit into the binary (closes #4)

A plain `docker build .` now stamps bsdaily's version: the VERSION build argument when one is given, otherwise `git describe --tags --always` on the .git in the build context, as the canonical Dockerfile does. The build fails if .git is there and the version still comes out empty, dev or unknown. A host `make` build stamps the same `git describe`, or dev. bsdaily logs the version on the first line of every run and prints it with --version; a build that stamps nothing, or an empty value, reports dev. Judgement call: the build line also takes the canonical -trimpath and -s -w. One //nolint (gochecknoglobals): -X can only set a package-level variable.

 # Completed Steps

+- 2026-10-06: A plain `docker build .` and a host `make` build stamp the git tag
+  or short commit into the binary, which `bsdaily` logs on the first line of
+  every run and prints with `--version`
+  (https://git.eeqj.de/sneak/bsdaily/issues/4).
 - 2026-10-06: Added the canonical `.golangci.yml`, moved the lint phase to
  golangci-lint v2.14.0, and fixed the code to pass it
  (https://git.eeqj.de/sneak/bsdaily/issues/6).
