Caution Review failedThe pull request is closed. WalkthroughThis update introduces minor refactoring and configuration changes across several server-side files. It adjusts import orders and formatting, adds a quota user parameter to Gmail API calls, serializes thread workflow processing by reducing concurrency, inserts a delay in thread synchronization, and appends a new database migration for the "ZeroAgent" class.

logic: Thread processing concurrency reduced to 1 - this may significantly impact processing throughput. Consider implementing a more granular rate limiting mechanism instead of reducing overall concurrency

logic: Using 'unbounded' concurrency for label fetching could cause rate limit issues. Consider setting a reasonable concurrency limit (e.g., 5-10).

Bug: Duplicate Class Declaration Causes Deployment Failures
The ZeroAgent class is redundantly declared as a new_sqlite_class in both the v2 and v4 migrations within wrangler.jsonc. This duplicate declaration causes deployment failures in Cloudflare Workers because a class cannot be marked as "new" in multiple migrations. This issue affects development, staging, and production environments.

Adding a second fixed 2-second sleep at the top of each loop iteration doubles the already existing delay later in the loop, unnecessarily slowing down thread synchronization and increasing the risk of the worker exceeding its execution time limits. Prefer using a single, well-justified delay or a back-off strategy inside withGmailRetry instead.

Comment is misleading: value sets concurrency to 1 but comment still says "up to 5 threads", increasing risk of future misconfiguration.
