feat(android): native mDNS discovery, host naming, touch mouse, stock selects

Discovery: replace the flaky per-OEM NsdManager with the same mdns-sd browse the Linux/Windows clients use, in the Rust core over JNI and polled by Kotlin (discovery.rs + nativeDiscovery{Start,Poll,Stop}); Kotlin keeps only the Wi-Fi MulticastLock + permission UX. IPv4-only (the core can't dial a bare/scoped v6 literal); daemon + fold-thread cleanup on every failure path; field sanitization so a rogue advert can't corrupt the picker snapshot. Discovery now starts regardless of NEARBY_WIFI_DEVICES (raw multicast only needs the MulticastLock) — a denial no longer kills it forever. ParseTxtTest replaced by ParseRecordTest. Hosts: hide already-saved hosts from the "Discovered" section (match by fingerprint, else address:port — mirrors the Apple client); add an optional Name field to the Add-host sheet and a Rename action on saved cards. Input: touch -> absolute mouse "direct pointing" like the Apple client — the host cursor follows the finger (new nativeSendPointerAbs -> MouseMoveAbs). Tap = left click, two-finger tap = right click, two-finger drag = scroll, tap-then-drag = left-drag, three-finger tap = HUD toggle. Settings: revert the dropdowns to the stock ExposedDropdownMenuBox look (a controller-focus UI will come separately); even out the Add-host field gaps. Docs updated (CLAUDE.md, client READMEs, docs-site status). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

+/// `NativeBridge.nativeSendPointerAbs(handle, x, y, surfaceWidth, surfaceHeight)` — absolute cursor
+/// position: the host moves the pointer to `x`/`y` in a `surfaceWidth`×`surfaceHeight` pixel space,
+/// normalizing against the size packed into `flags` as `(w << 16) | h` and mapping into the output
+/// region (it drops the event if that size is zero). This is the touch "direct pointing" path — the
+/// cursor jumps to the finger — and matches the Apple client's absolute touch forwarding.
