chore: release v0.26.14

The 0.26.14 block described the satellite dropdown being clipped, then
not following the list as it was edited — both repairs made to a feature
in the same block, on a machine no operator has ever seen. An entry only
earns its place if a reader could have met the problem: the feature is
announced once and the fixes are simply part of it.

The launch story was told four times over — the startup log, the profile
folder, the fixed-version runtime, the Edge blocker. They are one answer
to one question, 'it does not start', and read better as one. Same for
the two RDA entries: one list, one repair.

+// than stamping the band default — a wrong answer that looks authoritative. The

+// Chasing a split pile-up by the report the DX just sent.
+//

+// answers one station, sends "5NN", and moves on; the useful information is
+// therefore not the callsign it answered but the FREQUENCY that callsign was
+// transmitting on, because the DX's receiver was there a second ago.
+//
+// A CW skimmer already knows this. SDC (Software Defined Connector) decodes the
+// whole pile-up and marks each report on the panadapter as a spot — the marker
+// TEXT is configured in SDC by the operator ("599" for a fresh report, "X" for
+// an older one, by default). Those spots reach OpsLog already: it subscribes to
+// the radio's spot feed, and every spot another program posts arrives on
+// Flex.OnForeignSpot.
+//
+// So the whole feature is: recognise the marker, move the TRANSMIT slice there,
+// leave the receive slice on the DX. Nothing here decodes anything.
+//
+// Three deliberate choices:
+//
+//   - the marker text is a SETTING, not a constant. It is chosen in SDC, and
+//     any guess made here would be wrong for the operator who chose otherwise.
+//   - only the transmit slice moves, never the receive slice. Losing the DX is
+//     a worse outcome than a missed call.
+//   - the offset is signed and in Hz, because working "up a bit" from where the
+//     last station was answered is exactly how a pile-up is chased.
