fix(jenkins): isolate per-feed state/cooldown, cap posts, stagger batches

- Pass --state-path and --cooldown-path per feed so a rate limit on one
  feed no longer triggers a global cooldown that blocks all other feeds
- Add --max-posts 5 cap to prevent burst posting (e.g. 22 posts in one
  run) that was causing HTTP 429 errors on eurosky.social
- Add 15s sleep between batches to reduce cumulative API pressure
- Increase MAX_PARALLEL_FEEDS from 4 to 6 now that cooldowns are isolated
- Add MAX_POSTS_PER_FEED env var for central control of the post cap
- Fix missing line continuation backslash on --service argument

Fixes: batch 2-7 feeds being skipped due to shared cooldown state
