Extends MetricsProvider with thermals() returning a ThermalSnapshot
(battery_percent, battery_temp_c, cpu_temp_c — all optional). Each
provider implements it independently:

- AndroidMetricsProvider reads /sys/class/power_supply/battery/{capacity,
  temp} (battery temp is tenths of degC) and walks
  /sys/class/thermal/thermal_zone*, filtering by zone type
  (cpu/soc/tsens/core) so battery and skin sensors don't dominate the
  reading. Rejects nonsense values like INT_MAX from buggy zones.
- PsutilMetricsProvider uses sensors_battery() and
  sensors_temperatures() when present (Linux+laptops); no-ops on
  Windows/macOS where psutil doesn't expose them.
- NullMetricsProvider returns the empty snapshot.

PerformanceResponse gains battery_percent / battery_temp_c / cpu_temp_c.
The metrics-history ring buffer also carries cpu_temp / battery_pct /
battery_temp per sample so the dashboard can graph them over time.

Frontend dashboard (perf-charts.ts) gets a new Temperature chart card,
hidden by default and revealed only after seed/poll confirms the
backend reports cpu_temp_c. Battery temperature shows inline as a
secondary badge. The GPU card now also hides entirely when the backend
reports gpu=null instead of showing an "unavailable" placeholder.
HOST_ONLY_KEYS prevents the System/App/Both toggle from flipping a
non-existent app dataset for temp.

Tests: 6 new for thermals (battery tenths-of-degC parsing, CPU zone
filtering, fallback when sensors absent, INT_MAX rejection); 18 metrics
tests total; full suite 733 passing.

Beyond the `/proc`-based AndroidMetricsProvider that's now in place:
- [ ] Optional: app-specific memory via `Debug.getMemoryInfo()` through a Kotlin → Python Chaquopy bridge (more accurate than `VmRSS` for split-app-process accounting)
- [ ] Consider: device battery/temperature readings for TV boxes (some have thermal throttling)
- [ ] Optional: GPU usage via `/sys/class/kgsl/kgsl-3d0/gpubusy` on Adreno, Mali-specific paths for Mali GPUs
- [x] Device battery + thermal-zone readings (`/sys/class/power_supply/battery/{capacity,temp}`, `/sys/class/thermal/thermal_zone*/temp` filtered by zone type). Surfaced through `MetricsProvider.thermals()`, `PerformanceResponse.{cpu_temp_c,battery_percent,battery_temp_c}`, the metrics-history snapshot, and a new dashboard temperature chart that hides itself when the backend reports null. GPU card now hides (no "unavailable" placeholder) when no GPU is present.
