Summary

Adds npm run lighthouse-ci script that runs Lighthouse audits against built instance HTML files in instances/*/
Enforces configurable performance budgets via .lighthouserc.json (Performance >= 90, Accessibility >= 95, Best Practices >= 90, SEO >= 90)
Outputs a summary table to stdout showing each category score vs budget, exits with code 1 if any threshold is missed
Works in CI without a running server (uses LHCI's staticDistDir to serve files temporarily)

Files changed

package.json — new, with lighthouse-ci script and @lhci/cli dev dependency
.lighthouserc.json — new, budget thresholds and Lighthouse collect settings
scripts/lighthouse-ci.js — new, runner that discovers instances, runs Lighthouse, prints budget report
.gitignore — added LHCI temp file patterns
package-lock.json — generated lockfile

Test plan

Run npm install && npm run lighthouse-ci in an environment with Chrome available
Verify summary table prints with PASS/FAIL per category
Verify exit code 1 when a score drops below budget
Customize .lighthouserc.json budgets and confirm changes are respected
