v4

Release/2026-03-02 (#46)

* fix: forward review_model and reasoning_effort to validator step (#42)

The v3 refactor removed the hardcoded gpt-5.2/high fallback from
review-validator.ts but didn't add REVIEW_MODEL and REASONING_EFFORT
to the Prepare validator step's env block in action.yml. This causes
the validator pass to fall back to the Droid CLI's internal default
model instead of using the user's configured review_model.

* fix: pin upload-artifact to v4.6.2 SHA (#43)
