Add geospatial query performance regression tracker

[BigBen-7]

Description

Detect performance regressions in PostGIS spatial queries over time.

Requirements

• Query time tracking per radius
• Regression detection algorithm
• Alert on 20% slowdown
• Before/after deployment comparison
• Performance baseline management

Files to Touch

• analytics/app/geo-performance/page.tsx
• analytics/lib/regression-detector.ts

Complexity: 200 points

I'd like to work on this issue. It aligns well with performance engineering and observability. I'll implement a regression detection mechanism for PostGIS spatial queries, track query latency across the supported radius ranges, compare current measurements against historical baselines, surface alerts for regressions exceeding the configured threshold, and add a dashboard for before/after deployment comparisons. I'll also ensure the implementation is well-tested and documented. I'd be happy to take this on if it's available
