Keep Iroh enabled for the terminal client ABI

[lawrencecchen]

Problem

The Iroh default feature is now disabled for the normal cmux-tui dependency graph. The separate cmux-terminal-client C ABI is still an Iroh-only client, but its manifest inherited that new default and no longer enabled cmux-remote's iroh-transport feature. Workspace macOS clippy then failed with unresolved Iroh types.

Change

Enable cmux-remote/iroh-transport explicitly for cmux-terminal-client. This keeps Iroh out of normal cmux-tui builds while preserving the existing C ABI client's transport.

Validation

The release-path macOS arm64 build succeeded before this fix. Hosted verification will run clippy and the focused TUI test for this exact commit.

Summary by cubic

Enables the iroh-transport feature for cmux-terminal-client so the C ABI client retains Iroh support after the default feature change.

• The client previously inherited the disabled-by-default Iroh setting, breaking macOS clippy with unresolved Iroh types.
• Normal cmux-tui builds stay without Iroh; only the C ABI client enables the transport.

^{Written for commit e135d54. Summary will update on new commits.}
