P2 Badge Include the missing cache write tiers

This update only adds reasoning_budget, but the claude-opus-4-8 metadata still lacks the tier-specific input_cache_write_5m_cost_per_mil_tokens: 6.25 and input_cache_write_1h_cost_per_mil_tokens: 10 fields that the source issue says should be present. For Anthropic prompt-caching usage, especially 1-hour cache writes, consumers of this model metadata still cannot price the correct tier and may fall back to the generic 5-minute write cost or treat it as unknown, so the metadata remains incomplete after this fix.
