Missing LICENSE file: README references LICENSE.txt but no license is present #110

Hi, and thanks for the great work on the agent.

While reviewing the repository, I noticed that the README states:

Distributed under the Apache License. See LICENSE.txt for more information.

and shows an Apache license badge, but no LICENSE / LICENSE.txt file exists in the repository. GitHub also reports no license for this repo, and Cargo.toml does not declare a license field.

The other repositories in the organization (portabase, cli, old-agent, e2e-tests) all include an Apache-2.0 license file, so this looks like an oversight.

Without a license file, the default is "all rights reserved", which prevents downstream users from legally using, modifying, or redistributing the agent (for example when integrating it into other deployments or packaging it).

Would you consider adding the missing LICENSE.txt (Apache-2.0) and optionally a license = "Apache-2.0" field in Cargo.toml?

Thanks!
