`apps/web/vite.config.ts` now injects three build-time constants via
`define`: `__APP_VERSION__` (root package.json), `__APP_COMMIT__`
(GIT_SHA env > local `git rev-parse` > 'dev'), `__BUILD_TIME__` (ISO
timestamp at build). They're declared in `apps/web/src/global.d.ts`
and re-exported through `$lib/version` — components consume the named
exports rather than the magic globals so an accidental tree-shake
would break the test, not the page silently.
`/settings` gains an "About" section at the bottom: a small chip
`v{version} · {commit} · {date}` in muted text. Not interactive,
purely diagnostic — useful when a user reports a bug from a stale
PWA install.
Deploy pipeline:
- `apps/web/Dockerfile` accepts a `GIT_SHA` build arg and exports
it as an env var for the SvelteKit build step.
- `infra/docker-compose.erosi.yml` forwards `${GIT_SHA:-dev}` into
the build args.
- `infra/scripts/deploy-erosi.sh` captures `git rev-parse --short
HEAD` locally (the deploy host has .git; the remote doesn't —
rsync excludes it) and forwards it via `ssh ... env GIT_SHA=…`
so the remote `docker compose build` sees it.
V-01/V-02 vitest: stub the three globals via `vi.stubGlobal` (vitest
doesn't run through the main vite.config so `define` isn't applied),
assert the named exports thread through and never collapse to
undefined or the 'dev' sentinel under a real build.
