weekly-slack-scan

**Weekly Slack Scan**: Executes Jump 450's full weekly intelligence scan — reads every configured Slack and MS Teams channel, validates coverage and field completeness against fail-loud contracts, merges with assignments/forecast/pipeline/recruiting uploads, and writes a structured JSON data file that powers the Operations Insights web app. Use this skill whenever the user mentions: weekly scan, weekly slack scan, run the scan, scan slack, client briefing, run from [date] to [date], weekly report, slack callouts, or any request to generate the weekly executive briefing. This skill MUST be used for any weekly scan — never attempt it without following these steps. Each run MUST either read every configured channel or record it in `skippedChannels` with a reason; silent omissions are forbidden.
