fix(docker): give the practice-review worker its git checkout

[FelixTJDietrich]

Description

GIT_CHECKOUT_ENABLED is wired to application-server only. The worker is the role that runs agent jobs and bind-mounts a repository into the sandbox, and it is also where the health check looks:

// PracticeReviewHealthIndicator — worker role
if (!gitProperties.enabled()) {
    return Health.outOfService()
        .withDetail("reviewsEnabled", true)
        .withDetail("reason", "GIT_CHECKOUT_DISABLED")

So an operator who sets GIT_CHECKOUT_ENABLED=true and AGENT_ENABLED=true — the documented way to turn practice review on — gets a deployment that reports itself out of service and reviews nothing, because the flag never reaches the container that reads it. Staging has GIT_CHECKOUT_ENABLED=true set today and its worker container has zero occurrences of the variable.

What changes

The worker gets the same ${GIT_CHECKOUT_ENABLED:-false} the application server has. The default is unchanged, so a deployment that has not opted in is unaffected.

How to test

docker compose -f docker/compose.app.yaml config now renders the variable on both application-server and application-worker.

With AGENT_ENABLED=true and GIT_CHECKOUT_ENABLED=true, /actuator/health reports reviewsEnabled: true instead of GIT_CHECKOUT_DISABLED, and a queued review reaches the sandbox.

Checklist

• My changeset summary reads as an operator/user-facing note (it becomes the changelog entry) — see .changeset/README.md
• If the operator must act on this change (new required env var, manual migration step), the changeset summary says how (**Operators:** …) and MIGRATION.md is updated

No new variable and no operator action: this makes an existing setting reach the container that reads it. MIGRATION.md is untouched.

Summary by CodeRabbit

• Bug Fixes

  • Practice reviews now respect the application’s Git checkout configuration, preventing checkout-related failures.
  • Worker health indicators and repository access now accurately reflect whether Git checkout is enabled.
  • When enabled, practice review workers can access the required application repository for reviews.

• Documentation

  • Added release documentation for the checkout configuration update.

📝 Walkthrough

Walkthrough

The worker service now receives GIT_CHECKOUT_ENABLED, defaulting to false. A patch changeset documents the configuration alignment with the application server.

Merge Risk: 🔵 Low · up to 81c47

The worker configuration fix is localized and mergeable, but the generated changelog entry should be rewritten in operator-facing language so the behavior change is clear to users.
