improve: Implement CodeRabbit AI suggestions for better CI reliability

[codeunia-dev]

• Add Chrome setup step using browser-actions/setup-chrome@v1
• Simplify Lighthouse CI command to use existing lighthouserc.js config
• Update lighthouserc.js to use warn-level assertions with realistic thresholds
• Remove long CLI flags in favor of maintainable config file approach
• Ensures Chrome availability and prevents flaky CI failures

Summary by CodeRabbit

• Chores
  • Ensured Chrome is available during Lighthouse audits to improve CI reliability.
  • Simplified Lighthouse CI execution for more maintainable audit runs.
  • Converted Lighthouse assertions from failures to warnings and relaxed thresholds across performance, accessibility, best practices, and SEO metrics, reducing false failures while maintaining visibility into issues.

Walkthrough

Adds a Chrome setup step to the CI workflow before Lighthouse CI and simplifies the Lighthouse run command. Updates lighthouserc.js to relax thresholds and convert assertions to warnings across multiple metrics and categories.

Changes

Cohort / File(s)	Summary
CI workflow updates .github/workflows/ci-cd.yml	Inserts a "Setup Chrome" step before Lighthouse CI; replaces explicit lhci assert flags with a plain lhci autorun.
Lighthouse config thresholds lighthouserc.js	Converts assertion severities to warnings and relaxes thresholds (lower minScores, higher maxNumericValue for FCP, LCP, CLS, TBT, Speed Index).

Poem

I hop through pipelines, swift and bright,
Chrome now ready for the audit night.
LHCI hums with gentle warns,
Softer thresholds, fewer thorns.
Carrots cached, the build runs light—
Green meadows glow in dashboard light. 🥕✨

483-487: Bug: malformed FULL_HEALTH_URL (missing “?” before query params).

As written, the URL is invalid and will falsely fail the full health check when the bypass token path is exercised.

-              FULL_HEALTH_URL="$DEPLOYMENT_URL/api/health&x-vercel-set-bypass-cookie=true&x-vercel-protection-bypass=${{ secrets.VERCEL_BYPASS_TOKEN }}"

590-592: Make LHCI explicitly use the installed Chrome (export CHROME_PATH).

Occasionally LHCI fails to discover Chrome on runners. Since PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true, wiring the action’s chrome-path output removes that source of flakiness.

       - name: Setup Chrome
-        uses: browser-actions/setup-chrome@v1
+        id: setup-chrome
+        uses: browser-actions/setup-chrome@v1

       - name: Run Lighthouse CI
         run: |
           npm install -g @lhci/cli@0.12.x
           lhci autorun
         env:
+          CHROME_PATH: ${{ steps.setup-chrome.outputs.chrome-path }}
           LHCI_GITHUB_APP_TOKEN: ${{ secrets.LHCI_GITHUB_APP_TOKEN }}
           LHCI_TOKEN: ${{ secrets.LHCI_TOKEN }}

595-596: Avoid global install; use npx to speed up and simplify the step.

This removes the global install, reduces step time, and still pins the CLI version.

-          npm install -g @lhci/cli@0.12.x
-          lhci autorun
+          npx -y @lhci/cli@0.12.x autorun

23-31: LGTM: Warnings + realistic thresholds should curb CI flakiness.

Shifting key assertions to warn-level with pragmatic limits aligns with the stated PR goal and keeps visibility without blocking merges.
