/**
 * Unified schema for settings files
 *
 * ⚠️ BACKWARD COMPATIBILITY NOTICE ⚠️
 *
 * This schema defines the structure of user settings files (.claude/settings.json).
 * We support backward-compatible changes! Here's how:
 *
 * ✅ ALLOWED CHANGES:
 * - Adding new optional fields (always use .optional())
 * - Adding new enum values (keeping existing ones)
 * - Adding new properties to objects
 * - Making validation more permissive
 * - Using union types for gradual migration (e.g., z.union([oldType, newType]))
 *
 * ❌ BREAKING CHANGES TO AVOID:
 * - Removing fields (mark as deprecated instead)
 * - Removing enum values
 * - Making optional fields required
 * - Making types more restrictive
 * - Renaming fields without keeping the old name
 *
 * TO ENSURE BACKWARD COMPATIBILITY:
 * 1. Run: npm run test:file -- test/utils/settings/backward-compatibility.test.ts
 * 2. If tests fail, you've introduced a breaking change
 * 3. When adding new fields, add a test to BACKWARD_COMPATIBILITY_CONFIGS
 *
 * The settings system handles backward compatibility automatically:
 * - When updating settings, invalid fields are preserved in the file (see settings.ts lines 233-249)
 * - Type coercion via z.coerce (e.g., env vars convert numbers to strings)
 * - .passthrough() preserves unknown fields in permissions object
 * - Invalid settings are simply not used, but remain in the file to be fixed by the user
 */
