v0.3.2 — fix overlay crash on first show

v0.3.1 introduced TouchInterceptor (a FrameLayout wrapping the
ComposeView) so we could intercept touches before the inner MapView
saw ACTION_DOWN. That made the wrapper the window-root view (the
View actually attached to WindowManager) but I left the
ViewTreeLifecycleOwner / ViewTreeSavedStateRegistryOwner tags on
the inner ComposeView.

Compose's WindowRecomposer.create looks up findViewTreeLifecycleOwner
on the window-root, not on the inner ComposeView. With the tag
missing on the wrapper, Compose throws IllegalStateException at
composition startup — service crash on overlay enable.

Fix: move setViewTreeLifecycleOwner + setViewTreeSavedStateRegistryOwner
to the wrapper. v0.3.0 worked because the ComposeView itself was the
window-root then; the same pattern (owners on whatever's attached
directly to WindowManager) holds here.

+- **In-app**: the threat circle pulses while scanning; tap it to open the
+  bottom-sheet drill-down with per-source rows. DEFLOCK and CITIZEN events
+  carry coordinates — each row has a tap-to-open Maps icon (`geo:` intent).
+- **Foreground notification**: rebuilt on every threat-tier change. Title
+  becomes `OVERWATCH • RED` (or whatever tier); text shows the top
+  detection's score + label. Notification priority bumps to HIGH on RED so
+  the system can surface it as a heads-up.
+- **Vibration**: on upward tier transitions only. Short pulse for YELLOW,
+  double for ORANGE, escalating triple for RED. Toggle in Settings → Alerts.
+- **Per-source health**: the drill-down sheet shows orange `Source unreachable`
+  text on a row when its scanner couldn't reach its data source — silent
+  empty results vs. real failures are distinguishable.

+ * Dismiss zone:
+ *  - When the user begins dragging, a separate WindowManager view ([DismissView])
