- cmd/frontend/web: honour ?instance=<hostname> query parameter on the
initial scope hydration so /view/?instance=lb-ams opens the dashboard
scoped to that maglevd. The cookie is updated on consumption; an
unknown name still falls back to the first server via App.tsx.
- cmd/client, cmd/frontend: --server now accepts bare hostnames. A new
internal/netutil.EnsurePort canonicalises addresses by appending
:9090 when no port is given, with bracketing for bare IPv6 literals.
Unit test covers the IPv4/IPv6/bracketed/already-ported permutations.
- Makefile: new self-documenting `help` target as the default rule;
every user-facing target now carries a `## ` description that the
awk-based help auto-extracts. fixstyle-web skips with a friendly
message when prettier isn't installed instead of failing on npx.
