[aw-maintenance:failures-investigator] All agentic workflow runs blocked at activation: compile-agentic version v0.82.13 is on the blocked list

**Affected workflows**: all 22 agentic workflows in `githubnext/gh-aw-workshop` (lock files with `gh-aw-metadata.compiler_version: v0.82.13`), notably `Workshop Author` and `Workshop Builder`.

**Error signature**: every run 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** (representative sample; 43 total failures in the last 24h window, all with this signature):
- 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

- https://github.com/githubnext/gh-aw-workshop/actions/runs/33810480125

**Probable root cause**: The activation job's `Check compile-agentic version` step queries `https://raw.githubusercontent.com/github/gh-aw-actions/main/.github/aw/compat.json` for a block list of `compile-agentic` versions and fails the run if the workflow's compiled `GH_AW_COMPILED_VERSION` is present in that list. All lock files in this repository embed `compiler_version: v0.82.13` (visible in each `.lock.yml`'s `gh-aw-metadata` header comment), and `v0.82.13` is currently on the upstream blocked-versions list. This blocks every agentic workflow run before the agent job even starts — a total outage, not a per-workflow bug.

**Proposed remediation**: Upgrade the `gh-aw` compiler used by this repository to a version not on the blocked list, then recompile every workflow source (`.github/workflows/*.md`) to regenerate `.lock.yml` files with an updated `compiler_version` and updated pinned `github/gh-aw-actions/setup`/`setup-cli` action refs. Commit the regenerated lock files alongside any workflow-source changes required by the newer compiler.

**Success criteria**: A subsequent scheduled or manually dispatched run of any workflow in the repository (e.g. `Workshop Author`, `Workshop Builder`) completes the `activation` job's `Check compile-agentic version` step without the "Blocked compile-agentic version" error, and the agent job proceeds to execute.

Inspect the 22 `.github/workflows/*.md` sources and their generated `.lock.yml` files, especially the `gh-aw-metadata` compiler version, then compare it with `.github/aw/compat.json` and reproduce a representative activation run such as Workshop Author or Workshop Builder. Done means regenerated locks use an allowed compiler version and a subsequent scheduled or manually dispatched run passes `Check compile-agentic version` and reaches the agent job.
