Module config 

Engine configuration — hierarchical, hot-reloadable, command-line overridable.

Loads from engine.toml with sensible defaults for all settings. Supports:

• TOML serialization/deserialization
• Profile system (default, debug, release, steam_deck, low_end)
• Command-line argument overrides (--width, --height, --no-audio, etc.)
• Hot reload: watch engine.toml for changes and re-apply at runtime
• Validation with clamped/sanitized values
• Diff-based change detection for per-subsystem notifications
