chore: add package support metadata

[YfengJ]

Summary

• add the missing npm homepage link for the package
• add the missing bugs.url link to the repository issue tracker

Notes

• no runtime code, dependencies, package exports, generated files, or version fields changed

Verification

• node manifest assertion for homepage and bugs.url
• npm pack --dry-run --ignore-scripts --json
• git diff --check

---

Note

Low Risk
Manifest-only metadata with no runtime, dependency, or export changes.

Overview
Adds standard npm package metadata in package.json: a homepage pointing at the GitHub repo and a bugs.url entry for the issue tracker.

No runtime code, dependencies, exports, or version changes—manifest-only for registry and tooling discoverability.
