• Dates use YYYYMMDD format. Default: current month (1st to today).
• section_id defaults to WHOOING_SECTION_ID env var.
• Write tools resolve account types automatically from the account cache. Use whooing_accounts to look up account IDs first.
• Delete uses soft-delete (sets amount to 0 and prefixes item with [삭제]) due to a Whooing API limitation.
