v0.2.0

PCA9685 Debugging Panel v0.2.0 🎉

A significant update bringing internationalization, action recording & replay,
and improved developer experience to the remote servo debugging panel.

✨ New Features

🌐 Internationalization (i18n)

• Added bilingual support: English and Simplified Chinese (zh-CN).
• Language switch available in the settings modal; preference persisted across sessions.
• All UI text — status bar, channel cards, actions, modals — updates instantly on language change.

🎬 Action Recording & Replay

• Record a snapshot of all 16 channel positions (angle/pulse + calibration) as a named action.
• Actions are persisted to config.json and survive across restarts.
• One-click replay: restores all channels to their recorded positions using 3-tier smart
  calibration resolution (current → snapshot → raw duty fallback).
• Rename and delete actions from the actions grid.
• Default name "Action N" assigned automatically when recording.

🛠️ Debug Mode (--debug)

• Enable with python main.py --debug or pca9685-panel --debug.
• Per-request timing middleware shows request duration in the server logs.
• Full Python tracebacks in HTTP 500 error responses instead of generic messages.

🗑️ Clear Cache

• "Clear Cache" button in the settings modal allows users to delete all saved configs
  and actions with one click, resetting to factory defaults.

---

💅 Improvements

• JS-fail overlay: A bilingual warning overlay is now shown if JavaScript fails to load
  or crashes, so users without JS know the app won't work.
• Accessibility: aria-label attributes added to all form inputs.
• Enhanced action buttons: Improved layout and styling in the actions grid for
  better visual clarity.

---

🐛 Fixes & Maintenance

• Fixed duplicate object key in config.json causing potential config corruption.
• Cleaned up unused code in the frontend.
• Updated .gitignore for developer notes and local tooling files.
