feat: support teleport deployment and stage image in x-deploy

[AlexKaravaev]

This allows to:

• deploy over teleport, not only ssh
• use stage image as it's read-only and we need to mount /tmp there

Treat bare hostnames as SSH targets

looks_like_ssh_target only returns true when the target contains . or :, so valid SSH hostnames like localhost, orb-dev, or /etc/hosts aliases are misclassified as Teleport targets. In those cases resolve_remote_target calls tsh ls -v and fails to resolve instead of using SSH, which is a regression from the previous behavior where deploy always used SSH for the provided host string.

Useful? React with 👍 / 👎.

@copilot resolve the merge conflicts in this pull request

Resolved. Merged main into the branch and resolved the conflict in xtask/src/cmd/deploy.rs by combining both sides:

• From main: --bin flag on Args, deploy_bin function, get_crate_binary_name
• From HEAD: teleport/stage deploy support, deploy_deb with SSH+Teleport routing, get_package_deploy_info, bind-mount helpers

cargo check -p x passes cleanly. Merge commit: 947622e

@copilot fix clippy

Fixed in the latest commit. Two collapsible_if lints in looks_like_ssh_target and normalize_teleport_query were collapsed using if let ... && ... chaining. cargo clippy -p x --all-targets -- -D warnings now passes cleanly.
