v1.8.3

What changed

• Hardened update_transactions so it refetches every requested transaction after the YNAB bulk update, verifies requested fields persisted, retries mismatches once through update_transaction, and returns a verification block.
• Added live regression coverage for combined categoryId + approved batch updates.
• Added npm run smoke:batch-verify for stdio MCP smoke testing of review_unapproved, update_transactions, and post-write refetch verification.
• Documented that review_unapproved queue counts are not enough after approval batches and that manual transfer fixes can replace one side of a transfer pair with a new transaction ID.
