[DevOps] Set up performance regression gating in CI

[Xoulomon]

Suggested Tier: Medium (150 pts)

Description:
Catch performance regressions (contract gas, API latency, frontend bundle/LCP) before they merge.

Tasks:

• Track contract gas benchmarks and fail CI on a configurable regression threshold
• Add API latency benchmarks against a baseline in CI
• Add a Lighthouse CI budget for the frontend
• Store baselines and surface trend reports on PRs

Acceptance Criteria:

• A deliberate gas/latency/bundle regression fails the relevant CI gate
• PRs show a clear before/after comparison for tracked metrics
