Crate pathfinder_common 

Pathfinder Common — shared types, errors, and infrastructure.

This crate provides the foundational building blocks used by all Pathfinder crates:

• Error taxonomy — standardized MCP error codes (PRD §5)
• Domain types — SemanticPath, VersionHash, WorkspaceRoot
• Configuration — zero-config defaults + optional JSON override
• Sandbox — three-tier file access control
• Git integration — changed-file detection for repo map filtering
