PR Summary

Medium Risk
Changes the public ABI of VRNGConsumerAdvanced by replacing an immutable vrng variable with a vrng() getter returning address, which could affect downstream integrations. CI workflows also drop the global FOUNDRY_PROFILE, potentially altering build/test configuration.

Overview
Refactors VRNG consumer contract API. VRNGConsumerAdvanced drops the unused public immutable vrng field and replaces it with a vrng() view getter that returns the configured VRNG system address from storage; the _normalizeRandomNumber function pointer signature is also reformatted.

Tests/CI updates. Adds a test asserting the new vrng() getter returns the configured system, plus minor test formatting tweaks, and removes the top-level FOUNDRY_PROFILE: ci from the release.yml and test.yml GitHub workflows.
