• Added an entry to CHANGELOG.md if this change could be valuable to users

Summary

• Add a command to pipe the current editor selection through an external shell command (stdin → command → stdout replaces selection)
• Works with local and remote (SSH) workspaces — command execution goes through the proxy RPC
• Supports single selection only (Insert, Normal, and Visual cursor modes)
• Palette-based UI with command history and configurable options (output to new document, timeout)

Details

New command "Filter Through Shell Command" accessible via the command palette. When triggered, a palette opens where the user can type a shell command or pick from previously used ones. The current selection is sent as stdin to the command, and stdout replaces the selection. If nothing is selected, stdout is inserted at the cursor position.

Options available as toggles in the palette UI:

• New document — output to a new scratch document instead of replacing the selection
• Timeout — configurable timeout (5/10/30/60 seconds, default 5s)
