[FEATURE] Simplify coordination by reducing stage count to 1 per round

[cleanunicorn]

Problem Statement

The current swarm coordination system uses a 3-stage round structure that introduces unnecessary complexity for our simplified coordination use case. The multi-stage approach creates coordination overhead, delays round progression, and complicates the reward submission process for participants who need rapid feedback cycles.

Proposed Solution

Hardcode the stageCount constant to 1 instead of the current value of 3, effectively creating a single-stage round system where each round completes immediately after one stage.

Technical Details

• New functions/methods needed: N/A
• State variables required: Modify existing _stageCount constant from 3 to 1
• Events to emit: N/A (existing events will continue to work)
• Access control considerations: N/A

[Optional] Example Implementation

// Change this line in SwarmCoordinator.sol
uint256 constant _stageCount = 1; // Previously was 3

[Optional] Alternatives Considered

1. Dynamic stage count configuration: Would add unnecessary complexity for a parameter that should remain constant for network consistency
2. Parameterized constructor: Adds deployment complexity without clear benefit
3. Multi-stage support with single-stage mode: Over-engineering for the simplified use case
