Sprint 66 (Steps 889-898): Runtime Semantics Packs — framework and platform awareness

Adds 8 graduation headers: RuntimeSemanticsPack, RuntimePackLoader,
RuntimeAssumptionExtractor, RuntimeAwareLowering, RuntimeRaisingPolicy,
RuntimeVerificationPlugin, RuntimeCompatibilityRiskReport, RuntimeProfileStore.
MCP tools: whetstone_get_runtime_assumptions + whetstone_set_runtime_profile.
All 10 steps pass (86 tests total across sprint 66).
