/**
 * Bundled default model prices ($/million tokens).
 *
 * pi records `cost = 0` for token-priced / proxied providers it has no pricing
 * for (zai/GLM, 9Router `kr/…` `cx/…`, MiniMax, etc.). These defaults let the
 * panel show an approximate cost out of the box. They are merged under the
 * user's `~/.pi/agent/usage.json` `modelPrices`, so any user entry overrides
 * the matching default. Set your own with `/usage-pricing`.
 *
 * Figures are taken from each provider's official pricing page (June 2026):
 *   - Anthropic   platform.claude.com/docs/en/about-claude/pricing
 *   - OpenAI      developers.openai.com/api/docs/pricing
 *   - Google      ai.google.dev/gemini-api/docs/pricing
 *   - Z.ai (GLM)  docs.z.ai/guides/overview/pricing
 *   - MiniMax     platform.minimax.io/docs/guides/pricing-paygo
 *
 * Keys match a model ID exactly, or by base name (after the last `/`) so an
 * entry like `claude-opus-4.7` also covers `kr/claude-opus-4.7`. Prices change
 * often and subscription/proxy costs differ from list rates — treat these as
 * estimates and override as needed.
