Repair TransformerLab activation provisioning

 - The host-side install path assumes modern local tooling, but TransformerLab itself is provisioned from a pinned classic single-user layout.
 - TransformerLab is intentionally pinned to the older single-user `v0.28.2` release because newer upstream releases changed the project structure and behavior in ways that break this courseware.
 - This project does not rely on TransformerLab's upstream `install.sh`; the Ansible role provisions the pinned release directly so web assets, env layout, and runtime behavior stay reproducible.
-- The courseware repairs installed TransformerLab Fastchat plugin manifests so Fastchat-gated features such as Model Architecture and Visualize Logprobs stay available on pinned installs.
+- The courseware repairs the pinned TransformerLab install for symlink-aware plugin file lookups and refreshes installed Fastchat plugin manifests so Fastchat-gated features such as Model Architecture, activations, and Visualize Logprobs stay available on pinned installs.
+- The managed default TransformerLab student account is also seeded with the courseware Fastchat plugin plus the starter experiments and model metadata that `labctl up` depends on.
 - No Ollama models are pulled during `./labctl up`; students pull models manually as part of the courseware.
 - WhiteRabbitNeo assets are handled separately from `./labctl up` and `./labctl preflight`.
 - Run `./labctl assets lab2` when you want to populate repo-local lab 2 assets in `assets/lab2/` from Hugging Face.

-- bind `sshd` to `127.0.0.1:22` only
-- install WeTTY and expose it at `http://127.0.0.1:7681/wetty`
