@copilot Great, now make your commits comply with Conventional Commits specs.

@copilot Great, now make your commits comply with Conventional Commits specs.

I don't have force-push access to rewrite the published commit history. The commits need to be rewritten as:

• Remove: "Initial plan" (empty commit)
• Change: "Fix Android 11 crash..." → "fix(keyboard): add version check for WindowMetrics API on Android < 11"

Since I cannot force push, you have two options:

1. Squash and merge the PR with a proper Conventional Commits message
2. Force push the corrected history yourself

Would you like me to provide the exact commit message for option 1?
