// Antigravity CLI (`agy`) model catalog.
//
// These models are pinned from the live `:fetchAvailableModels` endpoint
// (https://daily-cloudcode-pa.googleapis.com/v1internal:fetchAvailableModels) using a
// real `agy` consumer-OAuth token. The public catalog exposes the same clean Gemini
// 3.5 Flash tier names as the Antigravity IDE provider; the shared Antigravity executor
// maps those names to the legacy upstream IDs immediately before dispatch.
//
// The `agy` provider reuses the `antigravity` executor/translator (identical backend),
// but ships its OWN catalog so it can expose models the `antigravity` provider's static
// list omits — notably the Claude models (`claude-opus-4-6-thinking`, `claude-sonnet-4-6`),
// which `:fetchAvailableModels` reports as user-callable with quota even though the
// `antigravity` catalog comment assumes they 404. Tab-completion models
// (`tab_flash_lite_preview`, `tab_jump_flash_lite_preview`) are intentionally excluded —
// they are not chat-callable.
