Merge branch 'main' into v1-dev

Resolved conflicts:
- src/modes/agent/index.ts: Kept v1-dev approach (user controls via claude_args)
- src/modes/review/index.ts: Kept deleted (review mode removed in v1-dev)

 - 📋 **Progress Tracking**: Visual progress indicators with checkboxes that dynamically update as Claude completes tasks
 - 🏃 **Runs on Your Infrastructure**: The action executes entirely on your own GitHub runner (Anthropic API calls go to your chosen provider)
 
+## ⚠️ **BREAKING CHANGES COMING IN v1.0** ⚠️
+
+**We're planning a major update that will significantly change how this action works.** The new version will:
+
+- ✨ Automatically select the appropriate mode (no more `mode` input)
+- 🔧 Simplify configuration with unified `prompt` and `claude_args`
+- 🚀 Align more closely with the Claude Code SDK capabilities
+- 💥 Remove multiple inputs like `direct_prompt`, `custom_instructions`, and others
+
+**[→ Read the full v1.0 roadmap and provide feedback](https://github.com/anthropics/claude-code-action/discussions/428)**
+
+---

 ## Quickstart
 
 The easiest way to set up this action is through [Claude Code](https://claude.ai/code) in the terminal. Just open `claude` and run `/install-github-app`.
