📄 Description

Describe your changes

In affected peer calculation, when walking policies of groups and peers, only use opposite sides of those policies; i.e. if a policy rule sources include the group, use the rule's destinations, and vice-versa. Similarly, if a rule's SourceResource matches a peer from the change set, use rule's DesstinationResource and vice-versa.

Summary by CodeRabbit

Refactor
- Improved how policy changes are analyzed to determine the affected peer and group impact, using directionally-derived extraction from policy rules for more accurate and deterministic results.
Tests
- Reworked resolver unit tests to validate precise affected peer/group sets derived from policy source/destination direction rules, including expanded coverage for mixed resource types and allowlist edge cases.
- Updated affected-peers coverage-matrix expectations and tightened assertions to compare exact included/excluded sets.
