v0.5.3

Fixed

• add a validated xiao settings carpet-avoidance [avoid|auto] command for the X20+ vacuum-extend carpet mode enum
• expose carpet_avoidance in the dashboard /api/settings snapshot for programmatic consumers
• keep compatibility with the raw Xiaomi escape label while presenting the safer user-facing avoid wording

• .venv/bin/ruff format --check src/ tests/
