-//! Subscription Manager for GRASP-02 Phase 4: Dynamic Subscriptions
-//!
-//! Manages dynamic subscription updates per connection, including:
-//! - Tracking subscribed announcements and events
-//! - Adding new subscriptions when announcements/PRs arrive
-//! - Consolidating filters when count exceeds threshold
-//! - Preventing duplicate subscriptions
-//!
-//! ## Dynamic Subscription Strategy
-//!
-//! Initial: Layer 1 (announcements)
-//!   ↓ (announcement received)
-//! Add: Layer 2 (events for that repo)
-//!   ↓ (PR/Issue received)
-//! Add: Layer 3 (events for that PR/Issue)
-//!   ↓ (filter count > 150)
-//! Consolidate: Back to Layer 1 only
