test_0_6_0.py -- tests for 0.5.9 / 0.6.0 features.

Covers: antipatterns, compare, conversation, sentinel, timeline,
weather, config (mood override + gate multiplier), and the three
new CLI subcommands (antipatterns, conversation, compare-agents).

All tests are self-contained — no GPU, no network, no real model.
