docs: Sync all documentation with Claude Code February 2026 features

Update 23 files across all 10 tutorial directories and 7 reference
documents to match the latest Claude Code v2.1+ features and correct
outdated content including model names (4.5→4.6), permission modes,
hook events, CLI syntax, MCP config paths, plugin manifest format,
checkpoint commands, session management, and URLs. Add documentation
for new features: Auto Memory, Remote Control, Web Sessions, Desktop
App, Agent Teams, MCP OAuth, Task List, Sandboxing, and more.

 #### Success Criteria
 - [ ] Code review skill automatically invoked when relevant
-- [ ] Pre-commit hook runs before git commits
-- [ ] You understand skill auto-invocation vs. hook triggers
+- [ ] PreToolUse hook runs before tool execution
+- [ ] You understand skill auto-invocation vs. hook event triggers

 #### What You'll Achieve
 ✅ Safe experimentation with checkpoints
 ✅ Planning mode for complex features
-✅ Headless mode for CI/CD
-✅ Fine-grained permission control
+✅ Print mode (`claude -p`) for CI/CD automation
+✅ Fine-grained permission control (default, acceptEdits, plan, dontAsk, bypassPermissions)
 ✅ Background task management
+✅ Auto Memory for learned preferences
+✅ Extended thinking via Alt+T / Option+T toggle
 
 #### Hands-on Exercises
 
 ```bash
 # Exercise 1: Try checkpoint workflow
 # In Claude Code:
-/checkpoint save "Before experiment"
-# ... make experimental changes ...
-/checkpoint rewind "Before experiment"
+# Make some experimental changes, then press Esc+Esc or use /rewind
