Subject: [PATCH] fix(ci): start Redis before the MCP server; fail fast when
 MCP never comes up

posthog services/mcp (hono) hard-exits without Redis at localhost:6379,
so every wizard-ci cell lost its MCP and reported an agent failure per
app. Start Redis first (docker/brew/apt per runner OS) and turn the
2-minute MCP readiness warning into a hard error so infra outages fail
one step early instead of burning a full agent run per matrix cell.
