Stale pricing for gpt-5.6-sol / gpt-5.6 / daybreak-blue-latest (OpenAI)

[github-actions]

What changed

OpenAI reduced first-party pricing for the GPT-5.6 Sol family. The catalog still carries the old rates.

Field	Catalog (stale)	Official (current)
input_cost_per_mil_tokens	5.00	4.00
output_cost_per_mil_tokens	30.00	20.00
input_cache_read_cost_per_mil_tokens	0.50	0.40

All three catalog entries — gpt-5.6-sol, gpt-5.6, and daybreak-blue-latest — carry identical stale values (gpt-5.6 has parent: "gpt-5.6-sol"; daybreak-blue-latest has fallback_models: ["openai.gpt-daybreak-blue-5.6-sol"]).

Note: input_cache_write_cost_per_mil_tokens (currently 6.25) is not listed on the OpenAI pricing page; left unchanged in the spec below. It may also need updating if OpenAI publishes a cache-write figure.
