Implement Exception Effect Registry and Evaluation Service

- Added IExceptionEffectRegistry interface and its implementation ExceptionEffectRegistry to manage exception effects based on type and reason. - Created ExceptionAwareEvaluationService for evaluating policies with automatic exception loading from the repository. - Developed unit tests for ExceptionAdapter and ExceptionEffectRegistry to ensure correct behavior and mappings of exceptions and effects. - Enhanced exception loading logic to filter expired and non-active exceptions, and to respect maximum exceptions limit. - Implemented caching mechanism in ExceptionAdapter to optimize repeated exception loading.

 ## Tasks
 ### T1: Exception Adapter Service
 **Assignee**: Policy Team  
 **Story Points**: 5  
 **Status**: TODO
 **Description**:
 Create an adapter service that converts persisted `ExceptionObject` entities from the Exceptions library into `PolicyEvaluationExceptions` records used by the Policy Engine.
 **Implementation Path**: `src/Policy/StellaOps.Policy.Engine/Adapters/ExceptionAdapter.cs`
 **Acceptance Criteria**:
 - [ ] `IExceptionAdapter` interface with `Task<PolicyEvaluationExceptions> LoadExceptionsAsync(Guid tenantId, CancellationToken ct)`
 - [ ] `ExceptionAdapter` implementation that:
  - [ ] Queries active exceptions from `IExceptionRepository`
  - [ ] Filters to only `Active` status exceptions
  - [ ] Filters to non-expired exceptions (expiresAt > now)
  - [ ] Maps `ExceptionObject` → `PolicyEvaluationExceptionInstance`
  - [ ] Maps `ExceptionType` + `ExceptionReason` → `PolicyExceptionEffect`
  - [ ] Creates scope from `ExceptionScope` (purl patterns, vulnerability IDs, environments)
 - [ ] Caching layer with configurable TTL (default 60s)
 - [ ] Cache invalidation event handler for exception status changes
 **Type Mapping**:
 ```csharp
 // From StellaOps.Policy.Exceptions.Models.ExceptionObject
 // To   StellaOps.Policy.Engine.Evaluation.PolicyEvaluationExceptionInstance
 // ExceptionScope → PolicyEvaluationExceptionScope
 // - purlPattern   → Tags (if component-based) or RuleNames (if policy-rule)
 // - vulnerabilityId → Sources (advisory source matching)
 // - environment   → Filter during loading
 ```
 ---
 ### T2: Exception Effect Registry
 **Assignee**: Policy Team  
 **Story Points**: 3  
 **Status**: TODO  
 **Dependencies**: None
 **Description**:
 Create a registry for exception effects that maps `ExceptionType` and `ExceptionReason` combinations to `PolicyExceptionEffect` instances.
 **Implementation Path**: `src/Policy/StellaOps.Policy.Engine/Adapters/ExceptionEffectRegistry.cs`
 **Acceptance Criteria**:
 - [ ] `IExceptionEffectRegistry` interface
 - [ ] `ExceptionEffectRegistry` implementation with predefined effect mappings:
 | ExceptionType | ExceptionReason | Effect |
 |--------------|-----------------|--------|
 | `vulnerability` | `false_positive` | Suppress |
 | `vulnerability` | `wont_fix` | Suppress |
 | `vulnerability` | `vendor_pending` | Defer |
 | `vulnerability` | `compensating_control` | RequireControl |
 | `vulnerability` | `risk_accepted` | Suppress |
 | `vulnerability` | `not_affected` | Suppress |
 | `policy` | `exception_granted` | Suppress |
 | `policy` | `temporary_override` | Defer |
 | `unknown` | `pending_analysis` | Defer |
 | `component` | `deprecated_allowed` | Suppress |
 | `component` | `license_waiver` | Suppress |
 - [ ] Effect includes routing template for notifications
 - [ ] Effect includes max duration days for time-boxed exceptions
 - [ ] Registry can be extended via DI configuration

 ### T3: Evaluation Pipeline Integration
 **Assignee**: Policy Team  
 **Story Points**: 5  
 **Status**: TODO  
 **Dependencies**: T1, T2

 - [ ] Existing `ApplyExceptions` logic handles the evaluation
 - [ ] Log exception application at Debug level
 - [ ] Emit telemetry counter for exceptions applied
 **Integration Point**:
 ```csharp
 // In PolicyRuntimeEvaluationService.EvaluateAsync:
 // 1. Load compiled policy bundle (existing)
 // 2. Load active exceptions for tenant (NEW)
 // 3. Build evaluation context with exceptions (existing, now populated)
 // 4. Evaluate policy (existing)
 // 5. Apply exceptions (existing logic)
 ```

 ## Decisions & Risks
 ### Open Decisions
 1. **Cache invalidation strategy**: Should we use event-driven invalidation or TTL-only?
   - Current proposal: TTL with event-driven invalidation as optimization
 2. **Audit trail storage**: Separate table vs. extending existing ledger?
   - Current proposal: New `policy.exception_applications` table for query efficiency
 ### Risks
 1. **Performance**: Exception loading adds latency to evaluation
   - Mitigation: Aggressive caching, batch loading
 2. **Cache coherence**: Stale exceptions might be applied
   - Mitigation: Short TTL (60s), event-driven invalidation for critical changes

 ## Decisions & Risks
 ### Open Decisions
 1. **Real-time updates**: SSE vs polling for exception status changes?
   - Current proposal: SSE via `ExceptionEventsClient` (already implemented)
 2. **Report format priority**: Which formats to implement first?
   - Current proposal: JSON (machine), PDF (compliance), NDJSON (streaming)
 ### Risks
 1. **UI component integration**: Existing components may need refactoring
   - Mitigation: Review components before wiring, plan refactoring if needed
 2. **Export performance**: Large exception sets may be slow
   - Mitigation: Async generation, streaming for NDJSON
