SFTP file transfers

Remote file browsing, the transfer queue, pause and resume, and how cancellation treats partial files.

Remote file browsing

A remote file tree with directory listing, read, write, rename, delete and create-directory operations.
Upload and download over SFTP (russh-sftp), reusing the same SSH session channel as the terminal.
Local and remote browsing share the RemoteFs abstraction, so local and remote panels behave alike.

Transfer queue

Every queued file is its own row, showing completed bytes against the total and the live transfer speed.

Directories and drag-and-drop uploads are walked once on the Rust side with walkdir.
Progress is reported in 4 MiB chunks; single-file uploads use 64 KB chunks.
Progress arrives through the transfer-progress event.

Pause, resume and cancel

Transfers support pause and resume.
Cancelling an upload cleans up the partial remote files created by that upload.
Files that already completed stay in place.
Target files that existed before the upload are not deleted.

Built-in network file tools

Besides SFTP, the application ships file-transfer tools that run from the same window:

FTP server with PASV and EPSV modes.
HTTP/HTTPS file server with one-click generation of a self-signed certificate.
TFTP server.
FTP client supporting no TLS, explicit TLS and implicit TLS.
