Pull request overview

This PR adds remote filesystem support for interactive cd functionality, enabling users to interactively navigate to remote filesystems (like SFTP) using the cd command with auto-completion.

Key Changes:

• Added CWD-aware path resolution for SFTP provider to support relative paths
• Enhanced interactive cd to pre-fill input with URL scheme for remote filesystems and call provider::absolute() for proper path resolution
• Refactored DisplaceDo actor into a separate file for better code organization

Missing initialization call yazi_shared::init_tests() in the Windows test. The Unix test at line 115 includes this call, but the Windows test is missing it. This inconsistency could lead to test failures on Windows if the initialization is required.
