v0.3.0 dev preview

Clipplane v0.3.0 dev preview

This release focuses on first-run activation for both Windows and macOS users.

Added

• New Windows setup wrapper: scripts/setup-windows.ps1 installs and verifies the Native Messaging host in one path.
• New macOS setup script: scripts/setup-macos.sh writes the browser Native Messaging manifest and generates a local launcher.
• New macOS checker: scripts/check-native-host-macos.sh verifies the manifest, launcher, Node runtime, and allowed extension origin.
• New npm shortcuts for Windows and macOS setup/check flows.

Improved

• npm run doctor now reports platform, Node version, browser native-host registration status, and actionable NEXT steps.
• Chinese and English README Quick Start sections now cover both Windows and macOS setup paths.
• Package and extension versions are now 0.3.0.

Verification

• npm test: 18 passed
• npm run smoke: passed
• npm run smoke:sync:local: passed
• npm run doctor: passed
• git diff --check: passed
• setup-windows invalid extension ID validation: passed

Notes

Clipplane remains a dev preview. Installation is still manual: load the unpacked extension, copy the extension ID, then run the setup script for your platform. The macOS Native Messaging path was reviewed from Windows but still needs a real Mac smoke test.
