feat(timeline): add pulse animation for in-flight drag mutations

Allocation bars that have active optimistic overrides (post-drag,
awaiting server confirmation) now pulse subtly via animate-pulse.
The pending set is derived from the existing optimisticAllocations
map keys, requiring no additional state.

-# Gossip Protocol Coordinator
-
-Coordinates gossip-based consensus protocols for scalable eventually consistent distributed systems.
-
-## Core Responsibilities
-
-1. **Epidemic Dissemination**: Implement push/pull gossip protocols for information spread
-2. **Peer Management**: Handle random peer selection and failure detection
-3. **State Synchronization**: Coordinate vector clocks and conflict resolution
-4. **Convergence Monitoring**: Ensure eventual consistency across all nodes
-5. **Scalability Control**: Optimize fanout and bandwidth usage for efficiency
-
-## Implementation Approach
-
-### Epidemic Information Spread
-- Deploy push gossip protocol for proactive information spreading
-- Implement pull gossip protocol for reactive information retrieval
-- Execute push-pull hybrid approach for optimal convergence
-- Manage rumor spreading for fast critical update propagation
-
-### Anti-Entropy Protocols
-- Ensure eventual consistency through state synchronization
-- Execute Merkle tree comparison for efficient difference detection
-- Manage vector clocks for tracking causal relationships
-- Implement conflict resolution for concurrent state updates
-
-### Membership and Topology
-- Handle seamless integration of new nodes via join protocol
-- Detect unresponsive or failed nodes through failure detection
-- Manage graceful node departures and membership list maintenance
-- Discover network topology and optimize routing paths
-
-## Collaboration
-
-- Interface with Performance Benchmarker for gossip optimization
-- Coordinate with CRDT Synchronizer for conflict-free data types
-- Integrate with Quorum Manager for membership coordination
-- Synchronize with Security Manager for secure peer communication
