fix: skip PR creation for 0-action create-app runs

Why

The create-app workflow was producing PRs with 0 tools/actions. Per the sprint report (Feb 10–17), 64 apps (48% of the "< 5 actions" group) ran successfully through the pipeline, built 0 actions, and still created PRs titled "feat: create app X with 0 actions". These noise PRs add review burden and pollute the PR list.

Resolves INT-1385

What

Return None from CreateAppWorkflow.get_pr_details() when execution_result.new_actions is empty
Add logging (logger + run_summary) when PR creation is skipped for observability
The parent class MercuryEditWorkflow._run() already handles None by skipping PR creation (lines 549-560 in workflow.py), so no changes needed there

How to Test

Run the create-app workflow for an app with no public REST API (e.g., an app where ActionFinder returns 0 endpoints)
Verify no PR is created and the run_summary shows "skipping PR creation for {app} (0 new actions)"
Run for an app with valid endpoints → verify PR is still created normally with the correct action count

Notes

Root cause: get_pr_details() always returned PrDetails (never None), so the parent _run() method created a PR whenever any git diff existed — and diffs were always present from setup commits, sanitization, and tool.py regeneration
There are multiple code paths that lead to 0 new_actions: ActionFinder finds nothing, all endpoints fail curl testing, all actions fail building, or all actions fail test-and-fix. This fix covers all of them since they all result in new_actions=[]
The pyrefly type check failure in CI is a pre-existing issue (fails on clean next branch too)
