twislaandClaude Opus 5.5 305818466f LoRa Scanner: MeshCore by default, and its public channel read
Site / build (pull_request) Successful in 9s
CI / build (pull_request) Successful in 2m19s
The MeshCore preset is the default for a new device, in the Settings and
in the radio before the Scanner is opened. The setting now accepts it:
it only took the 7 Meshtastic presets, so MeshCore picked in the App was
not saved.

Messages on MeshCore's public channel are decrypted with the channel's
published key (AES-128, checked with 2 bytes of HMAC-SHA256): the row
shows who says they sent it and the start of the text, the details the
sender, the time and the whole text. Other channels and private messages
stay encrypted.

twislaandClaude Opus 5.5 3339d9ee59 LoRa Scanner: MeshCore searches for nodes and their answers, read
The first two MeshCore packets heard were these: a search for repeaters
and a repeater answering. Both are in clear; they are the test's bytes.

twislaandClaude Opus 5.5 8ba41f72b6 LoRa Scanner: a MeshCore preset, and its packets read
- MeshCore joins the presets (EU/UK Narrow: 869.618 MHz, 62.5 kHz, SF8,
  CR 4/8, sync 0x12), after the Meshtastic ones so stored choices keep
  their number; `lora preset MeshCore` on the console
- lib/meshcore reads what MeshCore sends in clear: header, path, and a
  node's advert (name, kind, key, position)
- the list row, the details, a Capture's viewer and the console echo read
  a packet by the sync word it was received on
- the bandwidth is printed as 62.5, not 62

twislaandClaude Opus 5.5 2fce79aebd M3 step 4: the LoRa Scanner App, Sniffer and Captures
The Sniffer lists packets newest first (time, RSSI, SNR, and for
Meshtastic the sender, receiver and hops), with the clear header and a
hex dump on Enter (Q96); `p` picks an EU868 preset, kept in Settings
(Q95). `c` starts a Capture: pcap with LoRaTap in /captures/lora, its own
Clean-up category, recorded by a small Service so it carries on with the
App closed (Q97, Q100). The Status Bar shows L while listening, bright on
each packet, and CAP while capturing (Q101). StorageService gains raw
appends for binary files. Debug Builds get `lora inject` to test all of
this with no transmitter in range: a Capture made on the device reads
back in TShark field for field.
