Subject: Split monolithic status check.sh into modular check scripts

Replace the single-file prototype with independently-addable check
scripts (checks/*.sh) that each emit JSONL rows, a shared helper lib,
and one orchestrator/renderer (render.sh) that groups rows by section
and writes the static status page. A broken check script now shows up
as a down/warn row instead of crashing the whole render.
