v1.3.0

Added

• Packet positions can come from the MeshCore device's own GPS instead of
  the phone. A new "Packet position from" setting geotags captured packets with
  the position the connected radio reports — useful when the radio moves
  separately from you (mounted on a car while you measure from a laptop with no
  GPS, or on a dog's collar roaming a garden). With the device source selected
  the phone's location permission isn't required; "Center on me" and the map
  follow whichever source is chosen, and a "⚠ no position" note appears when the
  chosen source has no fix.
• The connected device's radio preset is shown in the header — the matching
  MeshCore regional preset (e.g. "EU/UK (Narrow)") for its frequency /
  bandwidth / spreading factor / coding rate, or the raw settings when nothing
  matches. The preset list is refreshed from the official source.
• The device's own node name is shown for USB and WiFi companions and USB
  repeaters (not just Bluetooth), and it is appended to saved non-Bluetooth
  devices — e.g. "USB: 1A86:7523 (MyNode)".
• Public-channel messages are decrypted and shown, via a new, much smaller
  packet decoder — a patched fork of @michaelhart/meshcore-decoder, maintained
  at github.com/kybl/meshcore-decoder.
• Trace packets show the per-hop signal (SNR) along the path in the packet
  detail.
• Suspicious "zero-stuffed" frames are flagged in the packet table and
  detail — long runs of leading zero bytes that are not real MeshCore traffic.
• The RSSI chart draws the radio's own measured noise floor as a dashed
  line, which also covers quiet stretches between packets.
• A date is shown next to any time that is not from today, so long
  multi-day captures are no longer ambiguous.
• A non-blocking "Loading…" notice appears at the bottom of the screen
  while rebuilding the view over a big capture — switching the Display window
  to a wide range, importing a large CSV, or resuming a large saved session;
  the page stays usable meanwhile.

Changed

• Battery level now shows on its own, without needing the official MeshCore
  client connected at the same time.
• The message filter searches the whole capture history, not just the
  currently loaded page.
• Auto-reconnect is more persistent on Android — it keeps retrying (a fast
  burst, then once a minute) while the background service is alive, retries the
  moment you return to the app, and shows "Pairing required" if the device asks
  to pair again. The ongoing notification clears when you disconnect on purpose.
• New per-packet sound: a short wooden "knock" marks a packet with a new
  hash, then each reception adds the SNR-pitched bell — so one packet heard via
  five repeaters is one knock plus five notes.
• The 3D-map controls moved onto the map itself (Center on me, Show all
  repeaters, and the settings gear beside the fullscreen button), the SNR
  chart's Incoming/Outgoing toggles moved below the chart, and the device's
  position marker is now a blue cone.
• The dark theme is easier to read — a neutral slate background instead of
  the old navy, with a brighter accent, clearer panel separation and brighter
  SNR/RSSI values, so the color comes from the data rather than the background.
  The light theme is unchanged.
• Faster cold start — the app preloads its whole module graph in parallel.
• Updated to target Android 16, as required by Google Play.

Fixed

• Some packets that previously showed a "Path payload too short" (or similar)
  error now decode correctly — the decoder's encrypted-envelope handling was
  corrected.
• The packet table no longer jumps back to the selected repeater's column on
  every incoming packet once you have scrolled it elsewhere.
• Accidental chart/map resizing is less likely — the resize handle is now
  only at the right edge instead of spanning the full width.
