ci / rust (push) Has been cancelled
feat: hosts grid + trust-on-first-use UX + settings pane
The app grows from a dev connect form into a real client shell:

- Home is a grid of saved hosts (UserDefaults-persisted; context menu: Remove / Forget
  Identity), "+" in the toolbar opens the add-host sheet, the stream mode moved into
  Settings (⌘, / gear) — native resolution stays the only mode, no scaling.
- Trust is now explicit: the protocol always supported certificate pinning, but the app
  passed no pin and discarded the observed fingerprint — silently trusting any host.
  First connect now shows the host's SHA-256 fingerprint (compare with the "clients pin
  this fingerprint" line in the host log) over the live-but-blurred stream; the stream
  must pump immediately (the opening IDR is the only guaranteed one), so StreamView gains
  a capturesCursor switch to keep the cursor free while the prompt needs clicking, and
  input capture starts only after confirmation. Trusting pins the fingerprint per host;
  a changed host identity then refuses to connect.
- PUNKTFUNK_AUTOCONNECT keeps working (auto-trusts, doesn't touch the saved hosts).

Host→client authorization (pairing PIN) remains a punktfunk-core roadmap item — the host
still accepts any client that can reach its port.
