Codex discovery falls back to DEFAULT_CONTEXT_WINDOW (272000) when upstream
omits context_window, which overwrote the previously-bundled 372000 hard
capacity for openai-codex gpt-5.6 luna/sol/terra on regen. OpenAI's Codex
model registry declares context_window = max_context_window = 372000, and a
direct Responses request with 350,317 input tokens completes, proving 272K is
not the route's hard cap.
Pinned these SKUs to 372000 in applyOpenAICatalogPolicy and refreshed the
bundled entries.
