Came up debugging the in-app update flow — wasn't obvious which image
the container was actually running without exec'ing in. New flow:
### Server
- internal/server/version.go: new `var ServerVersion = "dev"`,
overridden via -ldflags at build time.
- /healthz response gains a "version" key alongside the existing
"status" + "min_client_version". Backward-compat: existing clients
ignore unknown JSON fields. Endpoint stays unauthenticated.
### Build
- Dockerfile: new `ARG MINSTREL_VERSION=dev`, threaded into the
go build -ldflags so the binary's ServerVersion is stamped at
link time. Default "dev" preserves local `docker build` ergonomics.
- .forgejo/workflows/release.yml: tags step also emits a `version`
output (the git tag for tag pushes, "main" for branch pushes);
build step passes it as `--build-arg MINSTREL_VERSION=...`.
### Web
- web/src/lib/components/ServerVersion.svelte: small understated
text ("Server v2026.05.10.2") that fetches /healthz on mount.
Renders nothing on parse failure or pre-version images.
- Mounted at the bottom of Settings.
