chore: release v0.26.6

Panadapter spots are now worth reading. The comment carries the spotter, the
entity and the status in DXHunter's own shape — "CQ up 2 [F4BPO] [Franz Josef
Land] [New Slot]" — which needed two things nothing documents: SmartSDR splits
its command line on SPACES, so the words ran together until every space became
non-breaking; and it truncates past ~60 characters, so the cluster's own words
are trimmed first and the three brackets always survive. RBN column padding is
collapsed on the way in, or a preserved run of spaces opened a gap wide enough
to push the rest off screen.

"Already worked" means the CALLSIGN is in the log, not the entity: saying it of
a station never contacted was simply wrong. Each status can also be kept off the
panadapter entirely, and the WSJT-X decode spots obey the same switches — the
palette governs the panadapter, not one of the two things that feed it.

And the radio is no longer hammered: a spot whose frequency, colour and comment
are unchanged is not removed and redrawn. A busy skimmer feed re-spots the same
station every few seconds; one two-minute session sent 2128 adds, 88 of them for
a single callsign, and the display did not move a pixel for any of them.

CI-V, from an IC-7850 that kept killing JTDX: a reply the rig sent to another
controller on the same bus is no longer taken for ours, and a set_ptt, set_freq
or set_mode whose acknowledgement goes missing is verified by reading the rig
back instead of being reported as a failure. WSJT-X and JTDX answer a failed
command with a Rig Control Error and drop the link mid-over — 98 keyings, 6 lost
acknowledgements, 2 dropped connections in one session. The check waits 700 ms,
not the poll's 150: the rig has just failed to answer twice because it was
retuning, and a short probe would fail for the same reason.

Auto-call is withdrawn — it duplicated DXHunter, which already answers decodes,
and two programs deciding that from one shack key over each other. The library
is kept whole and dormant; a guard in App.tsx makes sure a stored preference
cannot key a transmitter whose switch no longer exists.

Also:
  - the log rotates while running, not only at startup: the CI-V trace left on
    wrote 416 MB and nothing would have stopped it before the disk did. Closing
    it now releases the crash file too — the runtime keeps its own duplicate.
  - the interface zoom announces itself, with a badge, a click back to 100% and
    a View menu; Ctrl+wheel and Ctrl+0 always worked and nothing said so.
  - no more elastic bounce, and no swipe-to-navigate out of the app.
  - Edit QSO: your own TX power and the contacted station's extended locator
    were saved and written back with no box to set them.
  - FT decodes: continents are a multiple choice; a compound MSHV message that
    answers two stations in one line is recognised as addressed to you.

+// The obvious source is the materialised award_refs column: it is already on
+// every row and one query reads it. It is also the wrong answer twice over.
+// That column holds DISPLAY LABELS, not references — depending on the award's
+// RefDisplay it can read "Krasnogvardeysky" or "ST-25 — Krasnogvardeysky", and
+// DXCC stores a country name — and it is a derived cache that lags: a QSO whose
+// references were back-filled (see BackfillRDA) counts on the Awards grid long
+// before anything recomputes its column. The first build of this badge used it
+// and marked a district worked on five bands as NEW.
+//
+// So the answer comes from the same place the Awards grid's answer comes from:
+// award.MatchQSO over the logbook. What is engineered here is the COST of that,
+// because the question is asked while the operator is logging:
+//
+//   - the set is per award CODE, and built only for codes actually asked about;
+//   - it reuses the award snapshot when one is already in memory, which it

+//     of it — the references of one award are a few thousand short strings;
+//   - and it is built in the BACKGROUND. A caller that asks before the set is
+//     ready is told so and gets no badge, never a wait and never a wrong badge.

+      "A QSO logged by WSJT-X, JTDX or MSHV now raises a notice in the corner naming the station. Watching the decodes, nothing else on screen said it had happened: the entry form never cleared, because nobody typed in it.",
+      "Icom CI-V: a reply the rig sent to another controller on the same bus is no longer mistaken for ours, and a PTT command whose acknowledgement goes missing is verified by reading the rig instead of being reported as a failure. WSJT-X and JTDX answer a failed set_ptt with a Rig Control Error and drop the link mid-over, which is what an IC-7850 was doing three times a session. The check itself waits 700 ms rather than the poll's 150: the rig has just failed to answer twice, usually because it is retuning — JTDX moves the transmit frequency and keys in the same breath — and a short probe would fail for the same reason. Both outcomes are logged, so a failure that remains can be told from a fix that did not fire.",
+      "FlexRadio: each spot status can now be kept off the panadapter entirely, with a switch beside its colours — and WSJT-X decode spots obey the same switches and the same colours. The palette governs the panadapter, not just one of the two things that feed it: statuses switched off still piled up on the waterfall because the decodes were pushed by another path.",
+      "Panadapter spot comments now read like DXHunter's: the cluster text, then the spotter, the entity and the status — \"CQ up 2 [F4BPO] [Franz Josef Land] [New Slot]\". The words were running together because SmartSDR splits its command line on spaces; non-breaking spaces get them through.",
+      "\"Already worked\" on a panadapter spot now means the CALLSIGN is in the log, not the entity. An entity worked on that band and mode is no news, and saying \"already worked\" of a station never contacted was wrong.",
+      "FT decodes: a compound MSHV message that answers two stations in one line — \"DM8BJF RR73; F4BPO <RI1FJL> +14\" — is now recognised as addressed to you when your callsign is in the second half.",
+      "Edit QSO: your own transmit power can be edited at last — the field was saved and written back but had no box, so a contact logged at the wrong power could never be corrected. The contacted station's extended locator gained a box for the same reason, and the power labels now say WHOSE power they are.",
+      "FlexRadio: a spot is no longer removed and redrawn when nothing about it has changed. A busy skimmer feed re-spots the same station every few seconds — one two-minute session sent 2128 spot adds, 88 of them for a single callsign — and the panadapter did not move a pixel for any of them.",
+      "Panadapter spot comments are kept within what the radio will accept: SmartSDR was cutting the longest ones mid-word, losing the entity and the status. The cluster's own words are trimmed first, the spotter, entity and status always survive. The column padding of an RBN line is collapsed to single spaces too — kept as non-breaking spaces it opened a gap wide enough to push the rest of the comment off the screen.",

+      "The elastic bounce at the end of a list is gone, and a two-finger horizontal swipe no longer navigates the window away from the app. Both are browser behaviours that only appear on a touchpad or a touchscreen.",
+      "The interface zoom now says what it is doing: a badge shows the factor while it changes, clicking it returns to 100%, and View → Zoom in / Zoom out / Actual size makes it findable. Ctrl+wheel and Ctrl+0 always worked, but nothing announced them — zoom by accident and there was no way back.",
+      "Icom CI-V: a frequency or mode change whose acknowledgement goes missing is now verified by reading the rig back, like the PTT already was. All three are commands WSJT-X and JTDX answer with a Rig Control Error and a dropped link, and an IC-7850 log shows a set_freq doing exactly that.",

WSJT-X et JTDX répondent à un set_ptt en échec par une erreur de contrôle radio et coupent la liaison en pleine émission — ce que faisait un IC-7850 trois fois par session. La vérification attend 700 ms et non les 150 de la scrutation : la radio vient d'échouer deux fois, en général parce qu'elle se réaccorde — JTDX décale la fréquence d'émission et passe en émission dans la foulée — et une interrogation brève échouerait pour la même raison. Les deux issues sont journalisées, pour distinguer un échec réel d'un correctif qui n'a pas agi.",

La palette régit le panadapter, pas seulement l'une des deux sources qui l'alimentent : les statuts décochés continuaient de s'entasser sur la cascade parce que les décodes passaient par un autre chemin.",

Les mots se collaient parce que SmartSDR découpe sa ligne de commande sur les espaces ; des espaces insécables les font passer.",

Le locator étendu du correspondant gagne une case pour la même raison, et les libellés de puissance disent maintenant à QUI elle appartient.",

+      "Les commentaires des spots du panadapter tiennent maintenant dans ce que la radio accepte : SmartSDR coupait les plus longs en plein mot, perdant l'entité et le statut. Le texte du cluster est rogné en premier, le spotteur, l'entité et le statut survivent toujours. L'alignement en colonnes des lignes RBN est aussi ramené à une seule espace : conservé en espaces insécables, il ouvrait un trou assez large pour repousser le reste du commentaire hors de l'écran.",

+      "Le rebond élastique en fin de liste a disparu, et un balayage horizontal à deux doigts ne fait plus quitter l'application. Deux comportements de navigateur qui n'apparaissent qu'au pavé tactile ou sur écran tactile.",
+      "Le zoom de l'interface s'annonce enfin : une pastille affiche le facteur pendant qu'il change, un clic dessus revient à 100 %, et le menu Affichage → Zoom avant / Zoom arrière / Taille réelle le rend trouvable. Ctrl+molette et Ctrl+0 fonctionnaient déjà, mais rien ne le disait — un zoom involontaire et on ne savait plus revenir.",

Les trois sont des ordres auxquels WSJT-X et JTDX répondent par une erreur de contrôle radio et une liaison coupée, et un log d'IC-7850 montre un set_freq faire précisément cela.",
