Summary

• consolidate repository command/result internals and related class responsibilities
• clean up runtime class lookups by trusting supported Pharo classes directly where available
• route debugger method implementor lookup through PharoCompatibility instead of MCP-local global probing

Dependency

• Depends on Add debugger implementor surface hooks PharoCompatibility#4 for PharoCompatibility debuggerMethodImplementorForSession:.

Verification

• PharoCompatibilityTest: 3 passed in Pharo 13
• MCPToolStructuredOutputTest: 31 passed in Pharo 13
• MCPDebugToolContractTest: 60 passed in Pharo 13
• MCPToolContractsTest: 114 passed in Pharo 13
• Targeted MCP searches find zero package references to #StDebuggerMethodImplementor, #CoverageCollector, or #StDebugger
• P12/P13/P14 runtime checks confirm the class availability assumptions
