v0.17.0 — Live countdowns, add-to-calendar, application status tracking
Three market-research-driven features for the opportunity feed:
- Live countdown timers on the opportunity detail page — ticking HH:MM:SS under 48h, days+hours otherwise.
- "Closing this week" filter chip on the feed, alongside category/region/audience filters.
- Per-opportunity Add to Calendar: single-event .ics download + Google Calendar quick-add link, distinct from the existing whole-feed/personal calendar subscriptions.
- Application status tracking on saved items (saved → applied → got it / no luck), with an aggregate "applications tracked" / "reported successes" count surfaced on the public /stats page.
