"""ml_settings: CCIP auto-apply switch + threshold (#114)

Confident CCIP character matches auto-tag (source='ccip_auto') on a daily sweep,
so identity tags keep flowing without pressing a button. ON by default (opt-out,
like head auto-apply); the high threshold (0.92, above the 0.85 suggest cut) +
single-character references keep it safe, and every auto-tag is reversible.
