feat: implement foundation - context cleanup and security (Part 1)

Browse Source 
This commit implements Part 1 of the policy refactor plan, establishing
a clean and secure context structure for Application-scoped policies.

Key Changes:

1. Security: Metadata Filtering
   - Added filterUserMetadata() to filter internal annotations/labels
   - Prevents policies from accessing system annotations (app.oam.dev/*,
     kubernetes.io/*, kubectl.kubernetes.io/*, etc.)
   - O(1) map-based filtering for performance

2. Explicit Context Fields
   - Added context.appName (instead of context.application.metadata.name)
   - Added context.namespace, context.appRevision, context.appRevisionNum
   - Added filtered context.appLabels and context.appAnnotations
   - All exposed via process.Context infrastructure

3. Controlled Application Spec Access
   - Added context.appComponents (components array only)
   - Added context.appWorkflow (workflow object only)
   - Added context.appPolicies (policies array only)
   - Prevents unintended access to full Application CR

4. Removed context.application
   - Completely removed to enforce explicit field access
   - Deleted cleanApplicationForPolicyContext() helper function
   - Forces security best practices

5. Removed context.prior
   - Simplified incremental policy feature (can be added back later)
   - Deleted associated test coverage

Test Changes:
   - Deleted 3 test blocks relying on removed features
   - Fixed TTL test expectation (CRD default is -1, not 0)
   - Fixed WorkflowStep struct initialization
   - All tests passing

Benefits:
   - ✅ Clean API with explicit fields
   - ✅ Security: No bypass to unfiltered metadata
   - ✅ Forces best practices
   - ✅ Simpler for policy authors
