description	Standardized preference keys, defaults, and migration-safe settings behavior for Wails backend + React frontend.

Skill 08: Preferences and Settings

Purpose

Ensure settings are stable, validated, and backward-compatible across releases.

Boundary

• Backend owns read/write persistence and migration.
• Frontend owns settings UI and validation hints.

Mandatory Rules

• Define all keys in one place.
• Always apply fallback defaults.
• Validate before save.
• Document migration when key semantics change.

Verification

• Tests for defaults and invalid-value fallback.
• Manual restart test to confirm persisted behavior.
