feat(executive-summary): add executive summary tab with WoW metrics, callouts, and data pipeline

[subodh2711]

URL for testing:

• https://feature-executive-summary-tab--forms-dashboard--adobe-rnd.aem.page/

Introduces a fully self-contained Executive Summary tab backed by a static JSON file extracted from HDFC weekly/monthly HTML reports.

Key additions:

• dashboards/executive-dashboard.js — shadow-DOM web component rendering hero, KPI strip (V1/EDS), callout signals (Wins/Watch/Action Needed), Week-over-Week 4-card section, weekly trends table, and monthly summary
• scripts/extract-hdfc-data.js — Node.js pipeline that parses HDFC report HTML into data/hdfc-executive.json (auto-discovers weekly wNN folders and monthly folders; no hardcoded lists)
• scripts/watch-reports.js — fs.watch wrapper that re-runs extraction automatically when report HTML files change
• package.json — adds "extract" and "watch:reports" npm scripts

Notable fixes in this branch:

• Banner summary extraction: switched from nested- regex terminator to start-position + 800-char window so banner.summary is never null
• Page Views delta colour: ▲ (more traffic) now correctly renders green
• Missing Resources KPI card: WoW delta added (was showing no trend)
• Callout order: signals panel moved above WoW cards for executive scan
• "Strong Signals" renamed to "Wins This Week" for executive clarity
• err-sig developer chips removed from callout items
• Dead code removed: wowBadge(), errorType(), errSigHtml(), .wow-row CSS, empty CSS rules, divide-x invalid property, duplicate @import font load
• Shadow re-attach guard added (connectedCallback idempotent)

Tests:

• tests/unit/executive-dashboard.test.js (39 tests)
• tests/unit/extract-hdfc-data.test.js (30 tests) All 121 unit tests pass.

Code Review

This pull request introduces an Executive Dashboard feature, consisting of a new web component for data visualization, a script to extract structured data from HDFC RUM reports, and a watcher for automated data updates. The dashboard includes sections for KPIs, week-over-week trends, and automated callouts for performance signals. Reviewers suggested optimizing the dashboard's mounting logic to prevent redundant re-renders, refining the deltaSpan utility to support neutral styling for zero-percent changes, and improving the data extraction script's portability and robustness by avoiding hardcoded paths and fixed-length string parsing.
