Docker image builds belong to the release workflow (tag-triggered).
CI now runs: go vet, go build (backend/runner/healthcheck), go test,
svelte-check, and UI vite build — fast feedback without Docker overhead.
Also triggers on all branches, not just main/master.
- Fix channel drain goroutine deadlock in handleRankingRefresh: replace
'for { ... continue ... if nil break }' with 'for A != nil || B != nil'
so the select never blocks on two nil channels
- Switch ScrapeRanking from urlClient (Browserless) to client (direct HTTP)
since novelfire.net/ranking is fully server-rendered — no JS needed
- Add ranking unit tests (single page, multi-page, empty page, write round-trip)
- Add .gitea/workflows/ci.yaml: lint, test, build jobs with commented-out
Docker image push step for when runner has Docker available
