feat: populate RepositoryURL from project registry in executor (ADR-007)

- Add GetProject to Store interface used by executor
- Resolve RepositoryURL from project registry when task.RepositoryURL is empty
- Call SeedProjects at server startup so the project registry is populated
- Add GetProject stub to minimalMockStore in executor tests
