Replaces the coarse density-bucket window_days with three InferredParams (all TTL=24h):
- lookback_days: min window containing ≥30 done events, capped at 30d (min_history=5)
- weekly_cycle: per-DOW peak-to-mean strength list (min_history=21, ≥3 weeks of signal)
- daily_cycle: per-hour peak-to-mean strength list (min_history=14)
compute() renders cycle hints when strength > 0.5:
"User tends to complete tips on Tuesdays and Saturdays."
"User is most active around 8pm."
Legacy window_days pref key still accepted as a fallback.
- window_days pref renamed lookback_days; backward-compat fallback in compute()
- Agent bumped to v1.2.0
- 19 new tests: weekend-warrior, weekday-only, evening-person, no-pattern,
legacy compat, snippet rendering with strong/weak signals
Closes#116
