v6.25.0 — live Unity log in the build step

Changed

• The Unity log is shown live in the build step. On the native lanes
  (self-hosted macOS / Windows, the Addressables pre-step, Unity tests and the
  Windows docker container) Unity writes only to its -logFile, so "Build
  with local Unity" showed just Unity binary: … for the whole build.
  scripts/build/run_unity_player.sh now follows the log file into the step
  output while Unity runs (tail -F), keeping Unity's exit code; the file is
  still written for the steps that parse and upload it. A log left by an
  earlier run is removed first so it is not replayed. UNITY_LOG_STREAM=0
  turns streaming off. GitHub masks registered secrets in the step output.

Tests

• A failed artifact-manifest or IPA-manifest upload (a full Actions storage
  quota) must not block the store uploads: both uploads keep
  continue-on-error, run before "Deliver the build", and the delivery step
  still receives job.status. Pinned in test_firebase_delivery_paths.py.

Upgrade: @v6 now points to this release. Pin @v6.25.0 for an exact version.
