* Parallelize Purview PSPC cold cache path
* Cache Purview payment-required state for scope refresh
* Cache Purview payment-required state for scope refresh
* Align Purview policy action dedupe and 402 caching
Deduplicate combined policy actions by action and restriction action so restriction-only actions are preserved
without duplicating identical entries. Cache tenant-level payment-required state from background scope refresh so
subsequent calls short-circuit consistently.
* .NET: Implement best-effort caching for background job scope retrieval and add unit tests for cache write failures
* Purview - feat: Enhance ScopedContentProcessor to queue ContentActivityJob when no applicable scopes are found and update related tests
* docs: Update purview package README and AGENTS documentation to reflect caching optimizations and policy enforcement scenarios
