[BUG] SSH Remote Development: "Could not spawn claude-ssh" on Linux — binary missing from .deb package

What's Wrong?

When configuring an SSH remote connection in Claude Desktop on Linux, the connection fails with:
Could not spawn claude-ssh

The app expects the claude-ssh binary at <resourcesPath>/claude-ssh/claude-ssh-linux-x64 (used to bootstrap the remote server). This directory is absent from the .deb package — the resources/ folder contains no claude-ssh/ directory.

This is distinct from #25659 (Windows hardcoded /usr/bin/ssh path) and #25661 (Identity File ignored). Here the SSH connection itself never starts because the helper binary is missing from the package.

What Should Happen?

The claude-ssh/ directory with the platform binaries and version.txt should be included in the Linux .deb package, matching the macOS distribution.
