feat(edge/p2p): complete RuVector advanced integrations

Browse source 
Added:
- Semantic embeddings interface with hash-based LSH encoding
- SemanticTaskMatcher for intelligent agent-task matching
- Raft consensus protocol for distributed task coordination
  - Leader election with term-based voting
  - Log replication with consistency checks
  - Heartbeat and append entries protocol

Now exports 20+ advanced types from p2p module:
- Quantization: ScalarQuantized, BinaryQuantized, CompressedData
- HDC: Hypervector, HdcMemory, HDC_DIMENSION
- Compression: AdaptiveCompressor, NetworkCondition
- Pattern routing: PatternRouter
- Vector index: HnswIndex
- Post-quantum: HybridKeyPair, HybridPublicKey, HybridSignature
- Spiking networks: LIFNeuron, SpikingNetwork
- Embeddings: SemanticEmbedder, SemanticTaskMatcher
- Consensus: RaftNode, RaftState, LogEntry, RaftVoteRequest/Response, RaftAppendEntries/Response

60 tests passing
