Change: Add CLI Reference Lesson

Why

The Claude How To repository covers nine major Claude Code features (01-09), but lacks a dedicated lesson for the CLI reference - the command-line interface that users interact with directly. Understanding CLI commands, flags, and options is fundamental to using Claude Code effectively. Users need a comprehensive reference to leverage features like model selection, output formats, permission management, and session handling via CLI.

What Changes

NEW 10-cli/ directory with comprehensive CLI reference lesson
NEW 10-cli/README.md - Main lesson content following established structure
UPDATE Root README.md - Add CLI lesson to navigation and learning path
UPDATE Root README.md - Add CLI to feature comparison and use case matrix
UPDATE LEARNING-ROADMAP.md - Include CLI lesson in learning progression

Key Content Areas

CLI Commands - Start interactive REPL, query mode, continue/resume sessions, updates
Core Flags - Print mode, continue, resume, version
Model Configuration - Model selection, fallback models, agent configuration
System Prompt Customization - Replace, append, file-based prompts
Tool & Permission Management - Allowed/disallowed tools, permission modes
Output & Format - JSON, stream-JSON, text formats
MCP Configuration - Server loading, strict mode
Session Management - Session IDs, forking, resumption
Advanced Features - Chrome integration, IDE connection, debug mode

High-Value Use Cases

CI/CD Integration - Headless mode with JSON output for automation pipelines
Script Piping - Process files, logs, and data through Claude
Multi-Session Workflows - Resume and fork sessions for complex projects
Custom Agent Configurations - Define specialized subagents via CLI
Batch Processing - Process multiple queries with consistent settings
Security-Conscious Development - Permission modes and tool restrictions
API Integration - Structured JSON output for programmatic consumption

Impact

Affected specs: None (new capability)
Affected code: Root README.md, LEARNING-ROADMAP.md
New files: 10-cli/README.md
