feat(cost): add Starveri API cost mapping

[Harsh23Kashyap]

Summary

Adds Starveri as a cost provider in packages/cost so requests routed through https://api.starveri.net get priced instead of showing unsupported or zero cost.

Closes #5692

Changes

• Register starveri provider with api.starveri.net URL detection
• Add endpoint pricing for all six public Starveri models from https://api.starveri.net/models
• Add registry entries for gpt-5.3-codex, gpt-5.3-codex-spark, gpt-5.4-mini, and gpt-5.5

Test plan

• cd packages && npx jest __tests__/cost/registrySnapshots.test.ts __tests__/cost/modelCostFromRegistry.test.ts

Someone is attempting to deploy a commit to the Helicone Team on Vercel.

A member of the Team first needs to authorize it.

Branch is current with main. Fork Vercel checks are blocked on deploy authorization. Please review when you have a chance.

Status update on the Starveri cost mapping PR.

This adds Starveri as a provider in packages/cost with URL mappings and endpoint pricing for six models from https://api.starveri.net/models. The work is split across three commits: provider setup, endpoint pricing, and registry snapshot tests.

Local verification: cd packages && npx jest __tests__/cost/registrySnapshots.test.ts __tests__/cost/modelCostFromRegistry.test.ts — 24 passed.

Branch is synced with main (behind_by: 0). Fork Vercel checks still need deploy authorization from the Helicone team — same pattern as my other open PRs on this repo.

Fixes #5692. Please review when you have a chance. I can adjust model coverage or pricing structure if anything looks off.
