feat: add headless Jira feature sync to daily launchd job

- New scripts/sync-jira-features.py fetches resolved tickets from Jira
  REST API v3, groups by parent Epic, and upserts features-released.csv
- launchd-sync.sh now runs Jira sync after PR sync and commits both CSVs
- .env / env.example updated with JIRA_EMAIL and JIRA_URL vars
