Implement hot/warm/cold context tiers with ContextTier, ActorRole, TieredFragment, TierBudget, ActorContextView, TierMetrics, and ScopedBackendView models. ContextTierService provides store/get, promotion/demotion with cold-tier summarisation hook, LRU eviction, per-actor filtered views (strategist/executor/reviewer), and project-scoped isolation via ScopedBackendView. Settings: context_max_tokens_hot, context_max_decisions_warm, context_max_decisions_cold. DI-wired as singleton context_tier_service. Includes Behave BDD scenarios (30), Robot Framework integration tests (7), ASV benchmarks (5 suites), and docs/reference/context_tiers.md. Closes #208
