chess 969efa5470 Avoid materializing writable-root carveouts for presence checks (#39812)
## What changed

- Add `FileSystemSandboxPolicy::has_writable_roots_with_cwd` to detect an
  effective writable root without constructing its read-only carveouts.
- Use the helper when classifying permission profiles and selecting patch
  rejection reasons.

## Testing

- Verify the presence check matches the existing materialized-root result
  across read-only, unrestricted, external, writable, denied, and unresolved
  special-path policies.
