Full changelog

migration: open NewIndexWriter once across all migration segments #287
Issue: Opening/closing Fjall DB per segment triggered an lsm-tree checksum error (ChecksumType mismatch) as data accumulated.
Fix: Instantiated NewIndexWriter once before the loop and passed it via &mut reference, avoiding the reopen failure path.
imap: Add fallback UIDVALIDITY support for non-compliant IMAP servers #288
Issue: Non-compliant servers (like Tencent Enterprise Mail) lack UIDVALIDITY, breaking sync.
Fix: Introduced generate_synthetic_uidvalidity() (hash-based) to enable incremental sync and system folder support.
