Cordn native: default crew tab to the private chat + founder nudge; release 1.6.1

- Crew page defaults to the Private-chat (MLS) tab when this device already has
  the group (useCordnGroupExists reads the IndexedDB snapshot — local only, no
  signer prompt); a manual tab click always wins.
- Founder/admin banner ('Set up') points at the tab when the crew has no group.
- Bump 1.6.0 -> 1.6.1 and add release notes for everything since 1.6.0 (private
  crew chat/MLS, self-hosted relay + media, marketplace close-the-deal, trust
  controls, map/weather, Clothing Designer, UI fixes).

+🆕 Private crew chat, end to end (MLS)
+- Crews now get a real encrypted group chat: RFC 9420 MLS through our own
+  self-hosted coordinator. Open a crew → "Private chat". Founders create it and
+  approve join requests; members tap "Ask to join". Roughly a second to join.
+- Send photos, copy the group link to open the same chat in Cordn or Staircase,
+  and your messages stay between members. The coordinator routes ciphertext and
+  metadata only — it never sees what you write.
+
+🔒 Our infrastructure, not someone else's
+- The community relay and photo/media storage now run on our own servers, so
+  your spots, crews and photos no longer depend on a third party. Same data,
+  faster and more independent.
+
+🛒 Marketplace: close the deal in-app
+- Accept an offer and pay right there (NWC / WebLN / Cashu), with the invoice
+  amount verified so you can't be overcharged.
+- Escrow now uses the mint the seller advertises, and confirmation is safer.
+
+🛡 Trust you can steer
+- Mute an account and it disappears everywhere (NIP-51 list).
+- "Alerts" flags accounts you follow that trusted people reported.
+- Choose your trust provider in Settings → Trust, and every badge says who
+  decided.
+
+🗺 Map & weather
+- Search now suggests spots and places as you type.
+- Spots show a 6-day forecast with a colour legend, sunrise/sunset, and a
+  manual refresh.
+
+🧵 New in The Lab
+- Clothing Designer joins the craft roles.
+
+🛠 Fixes & polish
+- Long menus scroll properly, and the language picker is searchable.
+- Spot cards are tappable across the whole card again.
+- Deleted spots no longer flash back from cache after a refresh.
+- Lighter on first load (CJK fonts download only if you pick that language).
