Run prettier on src/

Noticing a lot of weirdness in merges because of prettier being skipped

---

Important

Run Prettier on src/ to ensure consistent code formatting and prevent merge conflicts.

• Formatting:
  • Run Prettier on src/api/providers/fetchers/litellm.ts, src/api/providers/lite-llm.ts, and src/core/tools/__tests__/readFileTool.test.ts to ensure consistent code style.
  • Adjust line breaks and indentation in src/integrations/misc/__tests__/read-file-tool.test.ts and src/shared/__tests__/experiments.test.ts for better readability.
