SFTP backend now implements the complete Vfs trait with zero
Unsupported stubs. Three new operations:
- mkdir: creates directories via session.create_dir(). Supports
parents=true by walking path components and creating each missing
parent directory step-by-step via SFTP protocol calls.
- remove: deletes files and directories via session.remove_file() /
session.remove_dir(). Supports recursive=true by listing children
with read_dir() and removing them depth-first before the directory.
- rename: renames/moves via session.rename(oldpath, newpath).
Fixed 2 pre-existing warnings:
- Removed unused std::path::PathBuf import
- Added doc comment on SshHandlerError::KeyMismatch.host field
Updated module doc to reflect full read-write surface.
Updated README.md Phase 7 VFS status: 🚧 partial → ✅ complete.
1433 tests passing, zero warnings with --features sftp.
