feat(client): cross-target input handling + LAN mDNS discovery

Input handling, building on macOS/iOS/tvOS: - macOS recapture after navigating out: engageCapture no longer latches captured=true when the cursor grab is refused mid app-activation (which left a free cursor that no later click could re-grab); cursorCapture.capture() now reports success. + canBecomeKeyView. - iOS/iPadOS recapture: restore the prior capture on didBecomeActive (nothing re-grabbed mouse/keyboard on return before). - iPad indirect pointer (no lock) is forwarded as an absolute MOUSE (move + buttons + scroll via hover / UITouch.indirectPointer), not as touch, with the local cursor visible; GCMouse owns the locked regime, gated so the two never double-send. Adds the MouseMoveAbs wire helper. - Trackpad scroll on iOS (was entirely missing): GCMouse scroll dpad when locked + a scroll-only UIPanGestureRecognizer otherwise. - tvOS: no focusable control during play (a focusable Disconnect button ate the controller's A in the focus engine); Siri Remote Menu disconnects. - Don't leak touch to the host under the TOFU trust prompt (gate on captureEnabled). LAN discovery: HostDiscovery (NWBrowser over _punktfunk._udp, the host's crate::discovery advert) resolves each service to IP:port and parses the TXT (fp advisory, pair, id); an "On this network" section in the grid (tap to save + connect, or pair if required). iOS/tvOS get NSBonjourServices via a merged Config/Info.plist. Integration-tested end to end against a fake NWListener advert. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+// Advertise a fake punktfunk/1 host over real mDNS (NWListener) and assert HostDiscovery's
+// NWBrowser finds it, resolves an address+port, and parses the TXT (id / pair / fp). This
+// exercises the whole client discovery path on the loopback/LAN; it self-skips if the test
+// environment blocks Bonjour (sandboxed CI without local-network access).
