On page navigation the companion now briefly pauses and scans the
layout areas that changed. Center content is always scanned first,
followed by the right sidebar if a non-placeholder sidebar is
detected in the DOM.
Implementation:
- useRouteReaction.ts: thin orchestration hook that watches pathname,
determines changed areas, and chains triggerAttention calls via
setTimeout. Cancels on new route change, drag, or unmount.
- useBlobbiCompanion.ts: wires the new hook with existing
triggerAttention/clearAttention from useBlobbiAttention.
No changes to the attention system, state machine, gaze hook, motion
hook, or entry animation. The existing attending state and attend-ui
gaze mode handle all the visual behavior.
Includes an empty ROUTE_REACTIONS map for future per-route overrides.
