refactor(mcp): replace print() with logging in setup scripts
Replace direct print() statements with Python's logging module in MCP setup and verification scripts for better configurability and production readiness. Changes: - setup_mcp.py: Convert 30+ print() calls to structured logging - verify_mcp.py: Convert 40+ print() calls to structured logging - mcp_server.py: Convert 4 print() calls to structured logging - Preserve colored CLI output using logging formatters - Maintain all functional behavior (refactor only) Benefits: - Configurable log levels (debug/info/warning/error) - Better observability in production environments - Cleaner programmatic usage (no stdout pollution) - Professional logging practices Fixes aden-hive#833
