Shows a small message box with version metadata + build info. Used as
a fastest possible end-user smoke check after install: double-click
drover.exe in a portable bundle (or run 'drover gui' from cmd) and
see "OK — the binary launched and the Windows API is reachable" with
the right version on screen. No network calls, no admin needed.
Implementation: cgo-free, uses only golang.org/x/sys/windows (already
pulled in by the updater package). gui_other.go is a stub so the
package still compiles on Linux for the CI smoke build.
Locally verified: built with -X main.Version=test-local, ran
'drover.exe gui' on Windows 11, message box appeared with correct
version/commit/Go runtime info.

Adds a small, well-tested package that:
- Queries /api/v1/repos/root/drover-go/releases/latest (404 = no updates,
not an error).
- Compares the published tag against the running Version using
golang.org/x/mod/semver, so v0.1.0-rc.2 < v0.1.0. "dev" or any
semver-invalid current version is treated as "always update".
- Downloads the windows-amd64 asset + SHA256SUMS.txt, verifies the
sha256 of the binary against its line in the sums file (tolerates
the asterisk binary-mode prefix), and atomically swaps the running
exe via github.com/minio/selfupdate.
- Uses a 15s connect timeout with no overall request deadline, so
large asset downloads aren't truncated.
- Reports progress via an optional callback.
Public surface: Source interface + ForgejoSource implementation,
CheckForUpdate, ApplyUpdate, SetVersion. No GUI/cobra/Wails imports
in the package, so the same code is reusable from the CLI, the
Windows service, and the future tray UI.
Wires the package into "drover update" / "drover update --check-only"
in cmd/drover/main.go. --check-only exits 0 whether or not an update
is available; only network/sha/apply errors are non-zero.
Tests cover CheckForUpdate (table-driven incl. semver pre-release
ordering, dev fallthrough, source errors), parseSHA256Sums (text and
binary modes, CRLF, malformed lines, missing entries),
ForgejoSource.Latest (httptest with canned JSON, 404, 500, missing
asset, missing SHA256SUMS), and downloadAndVerify (success, sha
mismatch, HTTP 404, context cancellation). All run with -race.
Smoke-tested manually: built drover.exe and "drover update --check-only"
against git.okcu.io prints "No updates available" and exits 0 (no
releases yet).
