Branch: fix/no-sandbox-module-level-os-import
Commit Message: fix(sandbox): move os import to module level in NoSandbox.get_path
Milestone: (none — backlog)
Parent Epic: #397

Background

NoSandbox.get_path() in src/cleveragents/infrastructure/sandbox/no_sandbox.py imports the os module inside the method body rather than at the module level. This is a code quality violation — per PEP 8 and Python best practices, imports should always be at the top of the module.

Code location: src/cleveragents/infrastructure/sandbox/no_sandbox.py, inside get_path():

def get_path(self, resource_path: str) -> str:
    ...
    # Mark as active on first path resolution
    if self._status == SandboxStatus.CREATED:
        self._status = SandboxStatus.ACTIVE

    import os  # <-- inline import inside method body

    return os.path.join(self._original_path, resource_path)

Expected behavior: Per Python best practices and PEP 8, import os should be at the top of the module, not inside a method body. All other sandbox implementations (CopyOnWriteSandbox, GitWorktreeSandbox, OverlaySandbox) correctly import os at the module level.

Actual behavior: os is imported inside get_path() on every call, which is inefficient and inconsistent with the rest of the codebase.

Steps to reproduce:

Read src/cleveragents/infrastructure/sandbox/no_sandbox.py
Observe import os inside the get_path() method body
Compare with other sandbox implementations that import os at module level

Fix: Move import os to the top of no_sandbox.py at the module level, alongside the other imports.

Backlog note: This issue was discovered during autonomous operation
on milestone v3.5.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.
