/**
 * Model Validation (CLI subset copy)
 * Issue #588: Subset of cmate-cli-tool-parser.ts for CLI build (DR2-002)
 * Issue #989: Added Antigravity model name validation (Phase B)
 * Issue #2771: Added Claude model name validation
 *
 * This file duplicates MODEL_NAME_PATTERN, MAX_MODEL_NAME_LENGTH,
 * ANTIGRAVITY_MODEL_NAME_PATTERN, MAX_ANTIGRAVITY_MODEL_NAME_LENGTH,
 * validateCopilotModelName, and validateAntigravityModelName from the
 * server-side module to avoid importing server-only dependencies in the CLI build.
 *
 * Cross-validation test: tests/unit/cli/config/model-validation-sync.test.ts
 * ensures these values stay in sync with the canonical source.
