fix: avoid JSON import in ESM package

Why

Importing the published @openhands/typescript-client package root in Node ESM fails because the built dist/models/acp.js imports acp-providers.json without a JSON import attribute. This keeps issue #135 from being fully solved even though the package is published.

Summary

• Inline the ACP provider registry in TypeScript so the published ESM build no longer runtime-imports JSON.
• Keep acp-providers.json as the drift-check mirror and add a unit test to verify it stays in sync with the runtime registry.
• Replace the old git-dependency smoke test with a packed package install smoke test that imports the package root and required subpath exports, and run it in CI.

Issue Number

Fixes #135

How to Test

• npm run build
• node --input-type=module -e "import('@openhands/typescript-client').then(m=>console.log('ok', typeof m.RemoteWorkspace, m.ACP_PROVIDERS.codex.key)).catch(e=>{console.error(e); process.exit(1);})"
• npm test -- --runInBand src/__tests__/acp-providers.test.ts src/__tests__/package-import.test.ts
• npm run test:package-install
• npm run lint && npm test -- --runInBand && npm run format:check

Notes

test:git-dependency remains as a backwards-compatible alias for the new test:package-install script.
