/**
 * Return a UI hint for an Ollama model id, based on its parameter count.
 *
 * Examples:
 *   - `7b`, `8b`, `14b`, `72b` → `'✓ agent mode'`
 *   - `1.5b`, `3b`            → `'⚠ chat only (< 7B)'`
 *   - `custom-name` (no size) → `''` (no hint)
 *
 * The parameter count is parsed from the first `<number>b` token in the
 * id (case-insensitive), so both `qwen3:14b` and `llama2-13b` work.
