Willem Jiang 253fe4d87f feat(sandbox): harden local file access and mask host paths (#983)
* feat(sandbox): harden local file access and mask host paths

- enforce local sandbox file tools to only accept /mnt/user-data paths
- add path traversal checks against thread workspace/uploads/outputs roots
- preserve requested virtual paths in tool error messages (no host path leaks)
- mask local absolute paths in bash output back to virtual sandbox paths
- update bash tool guidance to prefer thread-local venv + python -m pip
- add regression tests for path mapping, masking, and access restrictions

Fixes #968

* feat(sandbox): restrict risky absolute paths in local bash commands

- validate absolute path usage in local-mode bash commands
- allow only /mnt/user-data virtual paths for user data access
- keep a small allowlist for system executable/device paths
- return clear permission errors for unsafe command paths
- add regression tests for bash path validation rules

* test(sandbox): add success path test for resolve_local_tool_path (#992)

* Initial plan
