Bug Fixes

• fix: remove incorrect StockRepurchasesEquity mapping for tax withholding concept (#760) — Removed a wrong gaap_mappings.json entry that mapped AdjustmentsRelatedToTaxWithholdingForShareBasedCompensation to StockRepurchasesEquity (confidence 0.364). Tax withholding on RSU vests is not a stock repurchase — the misclassification caused duplicate rows in the statement of equity for companies like AAPL.

• fix: add Q/YTD/FY period labels to equity and comprehensive income statements (#759) — Added StatementOfEquity and ComprehensiveIncome to the allow-list in rendering.py, so column headers now show friendly period labels (e.g., "Q1", "YTD") instead of raw date ranges, consistent with other financial statements.
