Implement auto-verification for plural-native workflows

[michaeljguarino]

• If we know a stack run is spawned by a workbench, auto-verify once it was successful
• figure out appropriate service equivalent.

Soffi AI Summary

This PR implements auto-verification for plural-native (workbench-driven) workflows — specifically for stack runs that are spawned by a workbench via an AI agent session.

Motivation: When a workbench AI agent creates a pull request that triggers an infrastructure stack run, there was no mechanism to automatically loop back to the workbench once the run completed. This PR closes that feedback loop: if a stack run succeeds and was initiated by a workbench job (via a PR), the system now automatically sends a verification prompt back to the workbench, asking it to confirm the expected infrastructure changes were applied correctly.

Key changes:

1. PR → StackRun association: A new stack_run_id foreign key is added to the pull_requests table (via migration), allowing a PR to be directly linked to the stack run it triggered. The for_stack_run/1 query helper is added to both PullRequest and WorkbenchJob schemas.

2. PubSub wiring: In the PullRequestUpdated event handler, after Stacks.poll/1 succeeds, the resulting stack run ID is now written back onto the pull request record. In the StackRunCompleted event handler, Workbenches.kick_workbench/1 is called so that workbench-linked runs automatically trigger the verification step.

3. Workbench kick logic: Workbenches.kick_workbench/1 looks up the workbench job associated with the completed stack run (via its PR), then posts a user-role message using a new EEx prompt template (priv/prompts/workbench/stack_run_verification.md.eex) that instructs the agent to do a verification pass on the completed changes.

4. Agent version bump: AGENT_VERSION bumped from v0.6.53 to v0.6.54.

Summary

68a8e5c

Implements the full auto-verification loop for workbench-driven stack runs: adds a stack_run_id FK to pull requests (with migration and schema query helpers), wires the completed stack run ID back onto its originating PR in the PubSub PullRequestUpdated handler, and introduces Workbenches.kick_workbench/1 which — on successful run completion — finds the associated workbench job and posts a verification prompt back to the AI agent. Adds tests covering both the PR→StackRun linkage and the workbench kick-on-completion path. Also bumps the agent version to v0.6.54.
