- Switch cli-hub analytics client from Umami to PostHog (us.i.posthog.com),
with agent/human classification derived from env vars and parent-process
names, and persistent analytics id at ~/.cli-hub/.analytics_id.
- Add daily deploy-pages step running .github/scripts/update_hub_analytics_stats.py
to pull PostHog totals into docs/hub/analytics-stats.json.
- Redesign docs/hub footer analytics panel (index.html + index-modern.html)
as a compact Apple/OpenAI-style card: live eyebrow, total, 2px ratio bar,
and inline Human/Agent split with percentages computed client-side.
- Expand cli-hub tests to cover the new analytics context fields and
provider switch.
