Remove all Raft protocol code

Removed all Raft-related code as it was not working properly:
- Removed VSRaftProtocol.java implementation
- Removed all Raft test files
- Removed Raft example/demo files
- Removed Raft documentation
- Removed Raft simulation files (.dat)
- Removed Raft scripts
- Updated VSRegisteredEvents to remove Raft registration
- Updated SimulationBuilder to remove RAFT constant
- Updated SimulationFactory to remove Raft methods
- Updated SimulationBuilderTest to remove Raft tests
- Updated pom.xml to remove Raft test configurations

The protocol had issues with leader election not completing in GUI mode.

-# Raft Simulation Testing Guide
-
-## What We Fixed
-
-The Raft simulation wasn't working because of a fundamental design issue with how protocols are activated:
-
-1. **Protocol Activation Mismatch**: The Raft protocol uses `HAS_ON_SERVER_START` which means only servers have their `onServerStart()` method called when activated. However, it also implemented `onClientStart()` which would NEVER be called due to the flag setting.
-
-2. **Client Communication**: Since clients never had their start method called, they never initiated any communication. We fixed this by having clients react to server heartbeats instead.
-
-## Changes Made
-
-1. Modified `VSRaftProtocol.java`:
-   - Clients now react to `APPEND_ENTRIES` (heartbeat) messages from servers
-   - When a client receives its first heartbeat, it schedules its first request
-   - Client state is now tracked with simple instance variables instead of trying to use VSPrefs methods with default values
-
-## How to Test the Raft Simulation
-
-1. **Build the project**:
-   ```bash
-   mvn clean package
-   ```
-
-2. **Create/Update the simulation**:
-   ```bash
-   java -cp target/ds-sim-1.0.1-SNAPSHOT.jar examples.RaftSimulationBuilder
-   ```
-
-3. **Run the simulator GUI**:
-   ```bash
-   java -jar target/ds-sim-1.0.1-SNAPSHOT.jar
-   ```
-
-4. **Load and run the simulation**:
-   - Click File → Open
-   - Navigate to `saved-simulations/raft-consensus.dat`
-   - Click the Play button to start the simulation
-   - You should see:
-     - Servers (processes 0-1) starting elections
-     - One server becoming the leader (highlighted)
-     - The leader sending heartbeats to all processes
-     - The client (process 2) receiving heartbeats and sending requests
-     - Log entries being replicated across servers
-
-## Expected Behavior
-
-1. **Initial State**: All servers start as FOLLOWERS
-2. **Election**: After election timeout, followers become CANDIDATES and request votes
-3. **Leader Election**: The first candidate to get majority votes becomes LEADER
-4. **Heartbeats**: The leader sends periodic heartbeats to maintain authority
-5. **Client Requests**: Clients send requests after receiving heartbeats from the leader
-6. **Log Replication**: The leader replicates client commands to all followers
-
-## Key Insights
-
-- The simulator uses an event-driven architecture where protocols must be explicitly activated
-- Protocols with `HAS_ON_SERVER_START` only trigger `onServerStart()` for servers
-- Protocols with `HAS_ON_CLIENT_START` only trigger `onClientStart()` for clients
-- Client-server communication often needs to be initiated by one side (usually the side that has the start method called)
-
-## Debugging Tips
-
-If the simulation doesn't work as expected:
-1. Check the console output for any error messages
-2. Verify that all 3 processes are created (0-1 as servers, 2 as client)
-3. Ensure the protocol activations are scheduled at the right times
-4. Look for the election timeout messages and leader elections in the logs
