fix: resolve monorepo type errors and stabilize build

This PR addresses several critical build and type-checking issues across the monorepo:

1.  **Core Package Stability**: Removed deprecated `baseUrl` from `packages/core/tsconfig.json` and converted absolute-style imports to relative paths. This allows `tsc --build` to succeed reliably.
2.  **Modern JS API Support**: Upgraded `lib` to `ES2023` in `packages/test-utils` and `packages/vscode-ide-companion` to resolve errors related to `Error.cause` and other modern JavaScript features.
3.  **SDK Type Integrity**: Fixed several `noImplicitAny` errors and resolved inheritance issues in `SdkTool` and `SdkToolInvocation` by refining generic constraints and adding necessary ESLint disable comments for complex type bypasses.
4.  **DevTools ESM Compliance**: Added missing `.js` extensions to relative imports in the DevTools client and fixed un-typed property access in log objects.
5.  **Build Graph Optimization**: Added missing project references in `test-utils` and removed redundant `paths` in `evals` to ensure correct build order and declaration resolution.

These changes collectively restore the ability to run `npm run typecheck` and `npm run build` across the entire project.
