Summary

Fixes #45 - IMAP connector skipping all existing emails during initial sync

Problem

The IMAP connector only syncs new emails but skips all existing/old emails in the mailbox. This happens consistently on every fresh ingestion setup, causing significant data loss.

Solution

Changed line 196 to initialize newMaxUids with the last successfully synced UID instead of the mailbox maximum:

- this.newMaxUids[mailboxPath] = currentMaxUid;
+ this.newMaxUids[mailboxPath] = lastUid || 0;
