- Consolidated build and deploy steps into single jobs - Removed separate build-cloudflare job that was causing artifact issues - Each deploy job now builds and deploys in the same runner - This ensures build artifacts are available for wrangler deployment - Should resolve the npx command failure in Cloudflare deployment

After the switch to Drizzle, findQuizById now returns content as the raw JSON string. getParsedQuizData passes that string directly into QuizDataSchema.safeParse without deserializing it, so validation always fails and submitAnswer/updateProgress will report parsing errors even for valid quizzes. Parse the JSON before calling safeParse (or return parsed content from the repository) to restore the previous behavior.

In the logged-in branch of getRandomGoodQuestion, the query inner-joins question_feedback and then filters with isNull(schema.questionFeedback.userId). Because question_feedback.user_id is defined as NOT NULL, that predicate is impossible to satisfy and the function always returns undefined, so authenticated users can never receive a random good question. A left join with a separate alias (or removing the null check) is needed.

Bug: Drizzle ORM Delete Result Property Error
The code attempts to access .changes property on the result of a Drizzle ORM delete operation. However, Drizzle ORM's delete result does not have a .changes property - this property exists only on raw better-sqlite3 statement execution results. This will result in undefined being logged and potentially cause runtime errors if this value is used in calculations elsewhere. The result from Drizzle's delete operation should be handled differently or the raw better-sqlite3 database object should be used instead.
