feat: build CLI core framework with Commander.js

Add CLI entry point with Commander.js, config management (~/.mcpctl/config.json
with Zod validation), output formatters (table/json/yaml), config and status
commands with dependency injection for testing. Fix sanitizeString regex ordering.
67 tests passing.
