[aw-maintenance:failures-investigator] Fix: gh-aw v0.82.13 is blocklisted, blocking all Workshop Builder/Author runs

**Affected workflows**: `Workshop Builder` (`.github/workflows/workshop-builder.lock.yml`) and `Workshop Author` (`.github/workflows/workshop-author.lock.yml`) in `githubnext/gh-aw-workshop`.

**Problem**: Every run of these two workflows fails in the `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.
```

**Affected run URLs**:
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33799237747
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33793552118
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33793370205
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33787391693
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33781459090

**Probable root cause**: Both lock files were compiled with `GH_AW_COMPILED_VERSION: v0.82.13`. The activation job's version-gate step fetches the current blocklist from `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json` and now finds v0.82.13 listed, so it hard-fails before the agent job can run. This is a total outage for these two workflows for the entire 24h lookback window — no run since the version was blocklisted has succeeded.

**Proposed remediation**:
1. Update the `gh-aw` CLI/extension to the latest non-blocked release in `githubnext/gh-aw-workshop`.
2. Recompile `.github/workflows/workshop-builder.md` and `.github/workflows/workshop-author.md` with `gh aw compile` to regenerate the `.lock.yml` files with the new `GH_AW_COMPILED_VERSION`.
3. Audit other workflow sources in the repo for the same stale `v0.82.13` pin and recompile those too.
4. Commit the regenerated lock files and re-run the workflows to confirm the activation job passes.

**Success criteria**: A subsequent run of both `Workshop Builder` and `Workshop Author` completes the `activation` job's "Check compile-agentic version" step successfully (no `##[error]Blocked compile-agentic version` message), and the agent job proceeds normally.

Start with .github/workflows/workshop-builder.md and workshop-author.md, then inspect their generated .lock.yml files for the v0.82.13 pin and review the current compat.json blocklist. Update gh-aw, compile both sources, and audit other workflow sources for the same version. Done means both workflows pass the activation version check and their agent jobs proceed.
