SEO: add 250 English-market city pages; auto-warm archives on deploy (#97)

Browse source 
The population-ranked global top-500 skewed to Asian megacities and missed
high-English-search-demand cities. gen_cities.py now tops up with the top ~250
cities from English-speaking countries (US/GB/CA/AU/NZ/IE/ZA) not already in the
global set, so US coverage goes 13->146, GB 2->42, CA 3->29, etc. (Seattle, Boston,
Manchester, Melbourne, Auckland, Dublin, ...). cities.json regenerated to 750.

Both deploy scripts now launch warm_cities.py automatically after the health check,
detached (dev: a systemd --user transient unit; prod: setsid/nohup), so the city
pages serve from cache without a manual step; idempotent, so only the first deploy
does the full warm. DEPLOY.md updated.

# Pre-warm the ~750 city-page archives so /climate pages serve from cache and a
# search-engine crawl never bursts the archive API quota. Detached + backgrounded
# so it never blocks the deploy or health check; idempotent (skips already-cached
# cells), so it's cheap on every deploy after the first full warm.
