chore(release): add channel packages to release workflow

- Bump channel package versions to 0.13.0
- Add publish steps for @qwen-code/channel-base and @qwen-code/channel-plugin-example
- Update version script to convert file: references to semver for published packages

This enables proper npm publishing of channel packages during the release process.
