v0.17.1

Field report (2026-08-05): on modern Expo/RN builds, app_state's
Metro-vs-embedded verdict relied on logcat markers (HMRClient/Fast Refresh/DevServerHelper) that some current dev clients don't emit, leaving
the bundle source unknown even when the app was live-connected to Metro.

Fix — a second, independent signal. When logcat gives no verdict,
app_state now reads the app process' /proc/<pid>/net/tcp[6] for an
established connection to a conventional Metro/Expo dev-server port (8081,
8082, 19000–19002) and reports metro from that instead. The response gains
bundle_signals (logcat and/or live_socket) showing which evidence the
verdict is based on. Logcat stays the primary signal — a live socket proves a
dev-server connection but not that the app is React Native — so the fallback
only fires when logcat is inconclusive. Unit-tested against real
/proc/net/tcp line formats.

Also closed out several open TODO/BACKLOG items to reflect current state: the
Maestro integration question is decided (defer — run_sequence covers batching),
batch-tap is folded into run_sequence, and the accessibility-action-tap and
Expo-dev-client-verification items are reframed as known open gaps rather than
untouched backlog.
