[aw-maintenance:failures-investigator] All agentic workflows fail at activation: compile-agentic version v0.82.13 is blocked

### Problem

Every agentic workflow in `githubnext/gh-aw-workshop` (44 failed runs in the last 24h, across at least `Workshop Student Simulator`, `Workshop Builder`, and `Workshop Author`) fails during the shared `activation` job at the "Check compile-agentic version" step with:

```
##[error]Blocked compile-agentic version: v0.82.13 is in the blocked versions list. Update gh-aw to the latest version and recompile your workflow.
```

This happens before any agent logic runs, so it is a hard, complete block on all agentic automation in the repository.

### Affected runs

- https://github.com/githubnext/gh-aw-workshop/actions/runs/33830050300
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33827596518
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33824685848
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33824666280
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33819608490

(and 39 additional failed runs in the same 24h window with the identical activation-step error signature)

### Probable root cause

The compiled lock files embed `GH_AW_COMPILED_VERSION: v0.82.13`. The activation job's version-check step fetches `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json` and finds `v0.82.13` listed as a blocked version, causing an immediate hard failure — evidence directly from the captured logs, not inferred.

### Proposed remediation

1. Update the `gh-aw` CLI/action dependency used to compile workflows in `githubnext/gh-aw-workshop` to a version newer than the blocked `v0.82.13`.
2. Recompile all workflow sources with `gh aw compile` so every `.lock.yml`'s embedded `GH_AW_COMPILED_VERSION` reflects the unblocked version.
3. Commit and push the regenerated lock files.

### Success criteria

- A subsequent run of any previously failing workflow (e.g. `Workshop Builder`) passes the "Check compile-agentic version" activation step.
- No new failed runs in the window show the "Blocked compile-agentic version" error signature.

Locate the gh-aw CLI/action dependency, the workflow sources, and the generated .lock.yml files. Update the dependency, run `gh aw compile` across the sources, and verify that a previously failing workflow passes the activation step "Check compile-agentic version" without the blocked-version error.
