quick bc we already have all the necessary indexes, no need for materialized views or anything yet. i've also only added the data point to the /project/:id endpoint

Pull Request Overview

This PR adds dependency and dependent counts to the /project/:id endpoint response. The change enhances the project endpoint by including two new fields: dependenciesCount (packages this project depends on) and dependentsCount (packages that depend on this project).

Key changes:

• Added SQL subqueries to count dependencies and dependents using existing database indexes
• Extended the project endpoint response with two new count fields

[Copilot]

The COUNT(*) subquery for dependenciesCount could be expensive for projects with many dependencies. Consider adding LIMIT clause or monitoring query performance, especially if this endpoint is frequently accessed.
