Closes: #17 Render Deployment Health Check Worflow

[p3ris0n]

feat: Add automated health check to prevent silent API outages

Description

This PR addresses the issue of the Render free-tier instance spinning down due to inactivity, which caused the first subsequent request to take 30+ seconds and allowed the service to experience silent outages without maintainers knowing.

A new GitHub Actions workflow acts as a heartbeat monitor. It pings the /api/v1/health endpoint every 6 hours to keep the instance warm. If the ping fails (returns a non-200 HTTP status), the workflow leverages actions/github-script to automatically alert maintainers.

To prevent issue spam during prolonged downtime, it implements a deduplication check: if an open incident issue already exists, it simply appends a comment to that issue rather than creating a new one.

Changes Made

• New Workflow (health-check.yml): Added a GitHub Action triggered via cron (0 */6 * * *) and manually via workflow_dispatch. Pings the live health endpoint and handles non-200 failures.
• Automated Incident Tracking: Uses github-script and the default GITHUB_TOKEN to manage issues with the incident label (no hard-coded secrets used).
• Documentation Updates: Updated the README.md to document the heart-beat ping operation and the incident label.
• Progress Tracker: Added a new entry to context/progress-tracker.md to log this architectural/ops change.

Testing & Verification

• Workflow triggers: Verified YAML syntax for both schedule and workflow_dispatch.
• Secret security: Validated that no secrets are committed to the codebase.
• CI: (Pending Actions run on this PR)
