Module node 

Raft single-group state machine.

Split across files:

• config: RaftConfig (including voter/learner lists).
• core: RaftNode struct, constructors, simple accessors, tick, propose, and the Ready output type.
• [internal]: Internal state transitions (elections, replication, commit advancement) and timeout math.
• membership: Dynamic configuration changes — add/remove voters, add/remove/promote learners.
• rpc: Incoming RPC handlers (AppendEntries, RequestVote, InstallSnapshot, and their response handlers).
