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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
