//! Model definitions and lookup.
//!
//! Maps our user-friendly model names to internal Antigravity identifiers.
//! The `model_enum` values are protobuf enum numbers extracted from extension.js:
//! placeholder models use 1000+N (e.g. M26→1026), while named models like
//! `MODEL_CLAUDE_4_OPUS` have their own enum values (e.g. 290).
//! See `docs/ls-binary-analysis.md` for the full enum mapping.

/// Model definition: friendly name → (antigravity_id, protobuf_enum, label).
