- Extracted the `tls-fetch` implementation and tests from `@oh-my-pi/pi-ai` to `@oh-my-pi/pi-utils`. - Exported the `wrapFetchForExtraCa` and `withExtraCaFetch` utilities publicly from `@oh-my-pi/pi-utils`. - Introduced `ExtraCaError` to replace the AI-specific `ValidationError` for missing `NODE_EXTRA_CA_CERTS` paths. - Updated imports in `packages/ai/src/stream.ts` to consume the relocated utility.
