Drizzle wraps the real D1 error in DrizzleQueryError.cause; both the access log and the origin-detect catch only logged .message, surfacing just "Failed query: <sql>" with no reason. Add formatError() to flatten the cause chain and use it at both sites so D1 failures are diagnosable. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* Drizzle wraps the underlying driver error in `DrizzleQueryError`, whose

|

* Logging just `.message` hides why the query failed — this surfaces the chain.
