Updated template agents to new architecture

[tonnitommi]

Description

Template agents were all using the old agent architecture. This PR updates them:

architecture: agent

to

architecture: agent_platform.architectures.experimental_1

And in addition each agent version is incremented with one minor.

How can (was) this tested?

This has NOT been tested by using all the template agents, only the yaml update has been done.

Screenshots (if needed)

Bump demo package version for architecture change

This changes the demo agent’s runtime architecture but leaves version: 0.1.1 unchanged, so consumers that key update behavior off version metadata cannot distinguish the old architecture: agent package from this new architecture build. That makes rollouts and cache invalidation ambiguous for this demo and can leave users on stale/incompatible packages even after the architecture migration.
