Bump version to 1.6.3 and add publish script for streamlined releases

[Copilot]

Overview

This PR adds a publish script to streamline the release workflow and bumps the package version to 1.6.3.

Changes

Version Bump

• Updated package version from 1.6.2 to 1.6.3 in package.json

New Publish Script

Added a new publish script to package.json that combines the build and publish steps:

"scripts": {
  "build": "bunx tsc",
  "publish": "bun run build && npm publish"
}

This allows maintainers to build and publish the package in a single command:

bun run publish

The script will:

1. Build the TypeScript source code using bunx tsc
2. Publish the compiled package to the NPM registry

Documentation

• Updated CHANGELOG.md with a new entry for version 1.6.3 documenting the addition of the publish script and version bump

Benefits

• Streamlined Workflow: Reduces the manual steps required to publish a new release
• Consistency: Ensures the build step always runs before publishing, preventing incomplete releases
• Developer Experience: Simplifies the release process with a single command

Testing

• ✅ Build process verified and working correctly
• ✅ Dry-run test of publish script successful (npm run publish --dry-run)
• ✅ No security vulnerabilities introduced

Original prompt

I need to bump and do another release with bun run publish
