What changed in this PR

Fixes particle animation in the existing Agent Radar canvas extension so in-flight particles follow the correct paths after graph rebuilds.

Changes:

• Reassigns particles to rebuilt links with matching endpoints and drops particles whose links were removed.
• Adds regression coverage for particle behavior when idle visibility and sub-agent state change.

File	Description
extensions/​agent-radar/​ui.html	Remaps in-flight particles to current links after each graph rebuild.
extensions/​agent-radar/​graph.test.mjs	Exposes particle state in the test harness and verifies link reassignment and removal.

This requires a version bump to the plugin otherwise clients aren't notified of the change and thus won't receive it.

[tkjaer]

Bumped the Agent Radar plugin version from 1.0.0 to 1.0.1 in df84c1c so clients detect the particle-path update.
