720a7d02f6 added a "workflow" arm to the scope help match that names workflow::HELP on every target, but mod workflow is #[cfg(unix)]. cargo check --target x86_64-pc-windows-gnu -p cmux-tui now fails with E0433, so the cmux-tui Windows check is red on every PR merged against current feat-cmux-next, for example https://github.com/manaflow-ai/cmux/actions/runs/41749887731/job/126312073998 on #26713.

This gates the arm with #[cfg(unix)] like the module. On Windows, cmux help workflow falls through to the root help, which matches how the workflow command is dispatched (Unix only).

Observed / Not run

• Observed: the E0433 at crates/cmux-tui/src/cli.rs:1206 in the linked Windows job.
• Not run locally: the Windows cargo check. This PR's own cmux-tui Windows check is the verification.

Summary by cubic

Fixes the Windows compile error in cmux-tui by gating the "workflow" scope help arm with #[cfg(unix)], matching the mod workflow module it references, and runs the related help test on Unix only. Also clears two clippy lints that fail -D warnings on the package. No behavior changes.

• On Windows, cmux help workflow falls through to the root help, matching how the workflow command is dispatched.
• Replaces a manual remainder check with is_multiple_of in teleport.rs and names the captured answer type Captured in automation.rs.

#34476 carries the same Windows fix and two clippy fixes and is ready-to-land; this PR becomes a duplicate when it lands. The cli/tests.rs cfg gate for the Unix-only test can follow as a small separate change if a Windows test lane needs it.

Superseded by #34476, which landed the same Windows workflow help gate and both automation clippy fixes on feat-cmux-next. One leftover for the owner: help_workflow_shows_the_workflow_usage_not_the_root_help in cmux-tui/crates/cmux-tui/src/cli/tests.rs is not #[cfg(unix)], so it would fail if the cmux-tui tests ever run on Windows (CI only runs cargo check there today).
