docs(README): refresh UIK version requirement and verification snapshot

Two staleness fixes after the 2026-04-08 dogfooding round:

1. The "Publishing state (the other side)" subsection said "UIK v0.2.1 or
   later required for the uik-daemon bin". v0.2.1 publishes device state
   correctly but the agent slot still goes stale after its TTL because
   that release only republishes the desktop heartbeat, not agent status.
   v0.2.2 fixes that by republishing agent status on the same
   POLL_INTERVAL_MS cadence. Updated the line to recommend v0.2.2 and
   spell out what each daemon release added so readers don't pin to a
   silently-broken version.

2. The "Latest local verification" snapshot was dated 2026-03-31 and
   referred to v0.5.0. Refreshed to v0.6.1 and 2026-04-08 with the actual
   dogfooded state (both devices and both agents active, zero stale,
   after the UIK 0.2.2 deployment). Left the claude-mem line on its
   original date because that path has not been re-verified since v0.5.0.

No code changes.

 The IDE Agent Kit and User Intent Kit are designed to be deployed together: IAK consumes the intent state for gating, UIK publishes your own heartbeats. Without the daemon your slot goes stale and other agents will treat you as offline.
 
-UIK v0.2.1 or later required for the `uik-daemon` bin.
+UIK v0.2.2 or later recommended for the `uik-daemon` bin. v0.2.0 introduced the daemon, v0.2.1 fixed a silent-exit in the example file, and v0.2.2 added agent-status republish on the heartbeat cadence so the agent slot does not expire while the daemon is running. Pre-0.2.2 daemons publish device state correctly but the agent slot still goes stale after its TTL.
