feat: Implement IsolatedReplayContext for deterministic audit replay
- Added IsolatedReplayContext class to provide an isolated environment for replaying audit bundles without external calls. - Introduced methods for initializing the context, verifying input digests, and extracting inputs for policy evaluation. - Created supporting interfaces and options for context configuration. feat: Create ReplayExecutor for executing policy re-evaluation and verdict comparison - Developed ReplayExecutor class to handle the execution of replay processes, including input verification and verdict comparison. - Implemented detailed drift detection and error handling during replay execution. - Added interfaces for policy evaluation and replay execution options. feat: Add ScanSnapshotFetcher for fetching scan data and snapshots - Introduced ScanSnapshotFetcher class to retrieve necessary scan data and snapshots for audit bundle creation. - Implemented methods to fetch scan metadata, advisory feeds, policy snapshots, and VEX statements. - Created supporting interfaces for scan data, feed snapshots, and policy snapshots.
