fix: Only validate SWOT section for uncited numbers

The uncited number detection was scanning the entire draft_report
including the Data Report tables (raw MCP metrics). This caused
18+ false positives since Data Report tables don't have [M##] citations.

Now extracts just the "## SWOT Analysis" section before validation.
