chore: add npm keywords and release 0.1.6

[ChuTingzj]

Summary

• Bump package.json version from 0.1.5 to 0.1.6.
• Add npm keywords aligned with the repo’s GitHub topics: sql, sandbox, docker, typescript, postgresql, mysql, npm, read-only, text-to-sql, ai-agents.

No source, sandbox image digest, README, or workflow changes. README and INTEGRATION do not hardcode the npm package version.

Publish

Do not tag in this PR. After merge to main, publish by pushing tag v0.1.6 (must match package.json version). That tag triggers .github/workflows/publish-npm.yml.

Test plan

• Confirm package.json is 0.1.6 and includes the keywords array.
• Confirm the diff is limited to package.json.
• After merge, push tag v0.1.6 and let publish-npm.yml publish.
