Greptile Summary

Added automated benchmark results for version 2.6.0. The data shows query latencies increased by 50-83% for most operations compared to 2.5.1, though all remain fast (sub-2ms). Native diffImpact improved by 17% (4.9ms vs 5.9ms). The hub target shifted from src/db.js to startMCPServer, indicating architectural changes that made the MCP server the most-connected node in the dependency graph.

Key observations:

• All percentage calculations verified and correct
• Table data matches embedded JSON structure
• Latency increases are consistent with benchmark methodology changes or codebase growth
• No functional or logical issues detected

Confidence Score: 5/5

• This PR is safe to merge with no risk
• Automated documentation-only update with validated data consistency, correct calculations, and no code changes
• No files require special attention
