fix(install): rebrand install script to the DeepAgent release line

- Usage/examples now point at https://deepagent.ltd/install (was the dead
  deepagent-code.ai domain)
- Download + version probes use the deepagent-ltd/deepagent-code releases
  (was the migration-era lessweb/anomalyco orgs)
- Version example updated to 2.0.0-beta.0; footer link -> ai.deepagent.ltd
