[Bug]: Provider refresh does not update cached skills after installing skills or plugins

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/server

Steps to reproduce

1. Connect a T3 Code client to a remote T3 server.
2. Open a project and let its skill list load.
3. Install a new skill on the remote machine under the same account and provider home.
4. In the local client, select the remote environment in Settings > Providers and click Refresh provider status.
5. Return to the same project and check the skill menu.

Expected behavior

Refreshing the provider makes newly installed skills available in the project’s skill menu without restarting the remote server.

Actual behavior

Newly installed remote skills remain missing from the local client and only seem to appear after restarting the T3 code server on the remote machine.

Workaround

Restart the remote T3 server, or disable and re-enable the affected provider in the remote environment’s settings, then reopen the project.

Start in apps/server by tracing the provider status refresh triggered from Settings > Providers and how the project skill list is cached. Reproduce the remote installation and refresh flow, then verify that newly installed skills appear without restarting the remote server.
