Closes#361
Three bugs in the hourly deploy workflow's change-detection logic caused the Play Store to silently fall behind whenever a deploy failed or all-android jobs were skipped.
**Bug 1 (primary): commit_sha → head_sha**
Forgejo's API returns head_sha; commit_sha was always None. This meant LAST_DEPLOYED_SHA was always empty, so the diff fell back to HEAD~1..HEAD — only the single most recent commit was inspected. If android changes landed in an earlier commit, they were silently missed.
**Bug 2: Skipped runs counted as 'deployed'**
A workflow run where deploy-playstore was skipped (android=false) has status=success, so it was treated as a successful deploy. Now the code queries each run's job results and only trusts a run where the 'Build & Deploy to Play Store' job's own conclusion=success.
**Bug 3: Narrow fallback when SHA unknown**
When LAST_DEPLOYED_SHA could not be determined the workflow diffed HEAD~1..HEAD — potentially missing many commits. Now it defaults to android=true / linux=true (deploy everything) as the safe fallback.
Additional changes:
- ::error:: / ::warning:: / ::notice:: annotations so skip/failure reasons surface in the Actions UI.
- scripts/verify_playstore_deploy.py: new post-deploy check that queries the internal track and fails if the latest version code is more than 1 hour old. (Version codes are Unix timestamps set by ci/main.go's PublishAndroid.) Catches silent deploy failures the upload API did not reject.
- scripts/test_verify_playstore_deploy.py: 5 unit tests for the verify script (all pass).
