v2.2.0: ESC behavior, filter nav, temp colors fix

- ESC no longer quits - clears filter or tree view instead (q to quit)
- Arrow keys in filter mode exit filter and navigate immediately
- Fix temperature colors: proper thresholds with/without sensor limits
- Mini-bars scaled to 100C for better visibility at normal temps
