analyze-cc-statements

Analyze credit card statement CSV files, categorize transactions, and produce a markdown spending report with month-over-month comparison. Activate when the user says "analyze my credit card statement", "analyze cc statement", "spending analysis for YYYY-MM", "categorize my transactions", "credit card report", "analyze-cc-statements", or provides a month argument like "2026-03" in the context of credit card or transaction analysis.
