[aw-maintenance:failures-investigator] Upgrade blocked compile-agentic version v0.82.13 causing all activations to fail

**Affected repository**: `githubnext/gh-aw-workshop` (all agentic workflows compiled with `gh-aw` v0.82.13)

**Error signature**: `##[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/33831291288 (Workshop Builder)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33830050300 (Workshop Student Simulator)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33827596518 (Workshop Builder)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33824685848 (Workshop Author)
- https://github.com/githubnext/gh-aw-workshop/actions/runs/33824666280 (Workshop Builder)

These 5 are representative of all 44 runs that failed in the last 24 hours in this repository — every one fails in the `activation` job at the `Check compile-agentic version` step with the identical message.

**Probable root cause**: The compiled `.lock.yml` files in this repository embed `GH_AW_COMPILED_VERSION: v0.82.13`. The `Check compile-agentic version` step (running `check_version_updates.cjs`) fetches `compat.json` from `gh-aw-actions` and finds v0.82.13 on the blocked-versions list, so it fails the `activation` job before any agent code runs. This is an infrastructure/version-gate failure, not an agent logic bug, and it blocks every workflow compiled with that gh-aw version.

**Proposed remediation**: Update the `gh-aw` CLI/action dependency in `githubnext/gh-aw-workshop` to the current unblocked release, then run `gh aw compile` (or the repo's equivalent compile command) to regenerate all `.lock.yml` files so `GH_AW_COMPILED_VERSION` is bumped past v0.82.13. Commit the regenerated lock files.

**Success criteria**: A subsequent run of any previously-failing workflow (e.g., Workshop Builder, Workshop Student Simulator, Workshop Author) passes the `activation` / `Check compile-agentic version` step and proceeds to its agent execution job.

In githubnext/gh-aw-workshop, inspect the gh-aw CLI/action dependency, the generated .lock.yml files, and the activation job's Check compile-agentic version step using check_version_updates.cjs. Update to an unblocked release, run gh aw compile or the repository's equivalent command, and commit the regenerated lock files. Done means a previously failing workflow passes the version check and reaches agent execution.
