PoPMobile v1.1.1

First APK build of the 1.1 series. v1.1.0 was tagged but never published with
a binary, so this release rolls up everything that landed since v1.0.14.

Added

• Live (windowed) hashrate. The hashrate display now reflects what the
  device is actually doing right now (10-second window) instead of a lifetime
  average that smeared over throttling events. Stops decaying to a fixed value
  and hard-zeroes once mining is stopped.
• User-configurable thermal + power protection. Settings now exposes
  pause / resume temperatures, a battery cutoff %, "require charging" toggle,
  and an "external power mode" for plugged-in stationary use. Replaces the
  hard-coded 70 / 60 °C defaults.
• Protection-state banner. A coloured banner above Start / Stop says why
  mining is paused, throttled, or running with reduced protections (battery
  cutoff, unplugged, thermal critical, cooling, sensor unavailable, external-
  power mode, etc.) — instead of failing silently.
• Battery Saver detection. When Android's Battery Saver is on, the banner
  shows "Battery Saver active — OS throttling" so a sudden hashrate drop
  isn't mistaken for an app bug.
• Temperature + banner stay live when stopped. Hitting Stop no longer
  freezes the TEMP / BATTERY / banner readouts at their last values; the
  thermal poller keeps running.
• PoPManager pairing QR scanner. Scan a pairing code from PoPManager
  instead of typing it. ZXing is bundled in the APK — no Play Services
  dependency, works fully offline.
• In-app Thermal Diagnostics card (Settings → Thermal Diagnostics).
  Lists every thermal zone the OS exposes, the one protection is acting on,
  PowerManager headroom + thermal-status bucket, SoC model, and a
  "Copy report" button so users on unsupported chipsets can paste a clean
  bug-report into a GitHub issue.

Changed

• Thermal-zone selection broadened for non-Snapdragon devices. Public
  Android temp-monitor apps all read from /sys/class/thermal/, but their
  advantage is the breadth of zones they recognize. We now scan both
  /sys/class/thermal/ and /sys/devices/virtual/thermal/, recognize more
  CPU/SoC hint zone types, and explicitly skip trip-point zones (which
  return the trip threshold instead of the live temperature) and the
  Qualcomm PMIC soc zone (battery state-of-charge, not temperature).
  Non-Snapdragon phones that previously showed -- should now show a
  real temperature.
• Battery percent now matches the OS status bar. Reads
  EXTRA_LEVEL / EXTRA_SCALE from ACTION_BATTERY_CHANGED first, falls
  back to BatteryManager.BATTERY_PROPERTY_CAPACITY. Several OEMs return
  a smoothed, fast-charge-aware capacity that lags the real value by 5-10%,
  so the in-app reading disagreed with the system tray (e.g. 90 % in app
  vs 95 % in OS).
• Battery cutoff is honored while plugged in. Previously the cutoff
  applied only on battery; the user's "stop at X %" preference now applies
  on AC too, so the device still trips at the threshold when plugged in.
• Resume hard-capped below Pause. The Resume slider can no longer be
  set above the Pause threshold (would have caused the engine to immediately
  re-pause on resume). Thread count is also restored to the user's setting
  after a throttle event instead of staying clamped.
• PoPManager error parity. "Pairing code expired" message now matches
  PoPManager's canonical wording so support docs line up across both apps.

Fixed

• Stop-mining restart regression in statsUpdateLoop — Stop followed
  by Start would leave the engine wedged because of a race between the
  stats loop and onNewJob. The two paths are now decoupled.
• Thermal-pause race + unbounded pool reconnect. A pause that landed
  during a connection retry could spawn a second reconnect loop racing
  the first; both paths are now re-entrancy-guarded.
• Invisible CRITICAL thermal alert. The stats loop was reading a stale
  thermalState from a register because the field wasn't @Volatile, so
  CRITICAL transitions never made it onto the banner — users only ever saw
  "PAUSED — cooling" instead of the actual cause.
• kotlinx.coroutines.isActive import in the thermal poller — release
  builds were failing to resolve it on some toolchains.
• MiningEngine LinkageError on new JNI methods. Devices upgrading
  from older builds with cached native libraries no longer crash the stats
  loop when a JNI method signature changes; the loop swallows
  LinkageError and keeps running.
• Settings crash on rotation caused by an early return inside the
  diagnostics-card composable.
• Slider integer truncation (thread count, temperature thresholds)
  was rounding to whole values mid-drag, plus a Compose hover-state crash
  on long-press of the slider thumb. Both fixed.

Notes

• versionCode 22, versionName 1.1.1, applicationId com.proofofprints.kasminer (unchanged — v1.0.x installs upgrade in place).
• v1.1.0's tag is left as-is for history; this release supersedes it.
