Fix Roo Code Nightly package.json generation

[cte]

Description

We weren't substituting roo-cline with roo-code-nightly in the generated package.json file if roo-cline appeared multiple times in a JSON node.

---

Important

Fix substitution issue in generatePackageJson and update test scripts and configurations for consistent vitest usage.

• Behavior:
  • Fix substitution issue in generatePackageJson in esbuild.ts to replace all instances of roo-cline with roo-code-nightly.
• Testing:
  • Update test cases in index.test.ts to verify multiple substitutions in generatePackageJson.
  • Add vitest.config.ts for Vitest configuration.
• Scripts:
  • Change test script in package.json files to vitest run from vitest --globals --run in build, cloud, telemetry, and types packages.
  • Update comments in test files to reflect new vitest command usage.
