A macOS build of acpmux fails on feat-cmux-next since #36564:

error[E0433]: cannot find `platform` in `crate`
   --> crates/acpmux/src/cli/entry.rs:214:58

The daemon enroll arm for non-Linux builds calls crate::platform::unsupported, but mod platform is #[cfg(not(unix))] (Windows only). On macOS the arm now returns its own error, daemon enroll runs only on Linux.

Red: cmux-ci dev build job 4aed088bf06e589b164bc0f8 (step tui-fetch) for #36084. That integration PR takes this commit and its dev build is the macOS check.

Summary by cubic

Fixes macOS builds of acpmux failing after the recent daemon enroll routing change.

• On non-Linux builds, daemon enroll previously returned crate::platform::unsupported, but that module only compiles for Windows, so macOS builds hit a compile error.
• The arm now returns its own daemon enroll runs only on Linux error instead.

^{Written for commit 48439bf. Summary will update on new commits.}

Subagent correctness review of 48439bf: no findings. The two DaemonEnroll arms (linux / not linux) are exclusive and exhaustive on every target; the variant is not cfg-gated; ffcb907 added no other platform:: use. Primary check: same reading. macOS compile evidence comes from the cmux-ci dev build of #36084 at abbfb1257716e6dd8b43b8c577e65bba07d91466, which contains this commit.

Correction to the comment above: the integration head that contains this commit is abbfb12 (a typo gave abbfb1257716…). Its macOS dev build is cmux-ci job 84cb501061b6a88b32042f66; job 352bd4e43d7f826f13eabe6b failed only on the mistyped SHA.

macOS compile evidence: cmux-ci dev build job 84cb501061b6a88b32042f66 at abbfb12 (contains 48439bf) succeeded, including acpmux for the Mac target; job 4aed088bf06e589b164bc0f8 at 3e9d593 (without it) failed with E0433. Labelled ready-to-land.

MERGE QUEUE: merged to fix the tip compile red (STATUS 14750, culprit #36564). Fleet compile-check f1fe6d301544ce6c76d6f2af at 48439bf, recipe 2: CmuxNext pass, app pass, macOS cmux-tui cargo check pass. Linux clippy (changed cmux-tui packages) pass. Every other crate::platform:: use in acpmux sits under #[cfg(not(unix))]; this arm was the only one reached from macOS.
