Add analytics page

[amrit110]

This pull request introduces a comprehensive weekly GitHub metrics collection workflow, updates the deployment process to auto-publish analytics when metrics are updated, and refreshes the site’s visual style to align with the Vector Institute brand. It also updates documentation and pre-commit settings to support the new analytics features.

GitHub Metrics Collection & Automation:

• Adds a new .github/workflows/collect-metrics.yml workflow to automatically collect and commit GitHub repository metrics weekly, with data validation, commit logic, and summary reporting.
• Updates .github/workflows/deploy-catalog.yml to auto-trigger deployment when metrics are updated, ensuring the analytics dashboard is always current. Also adds a condition to only deploy if metrics collection succeeded. [1] [2]

Analytics Dashboard & Documentation:

• Updates README.md with a new section describing the analytics dashboard, its features, and instructions for manual and automated metrics collection, including token requirements.

Pre-commit & Data Handling:

• Modifies .pre-commit-config.yaml to exclude the new metrics data files from typo checks, preventing unnecessary linting on generated analytics data.

Branding & Visual Refresh:

• Overhauls color variables and gradients in catalog/app/globals.css and updates UI components in catalog/components/hero.tsx and catalog/app/page.tsx to use the official Vector Institute color palette, improving visual consistency and branding across the site.
