fix: parse minimally-quoted csv rows when loading jobs.csv

csv.ts

+// Parse one jobs.csv line. The file holds both fully-quoted rows (what
+// index.ts writes) and minimally-quoted ones (any tool that rewrites the CSV,
+// e.g. Python's csv module, only quotes fields containing a comma). Splitting
+// on '","' only understands the first form — every minimally-quoted row came
+// back with no link, so index.ts re-added old jobs as new and daily.ts
+// couldn't dedupe against them.
