[rust-launcher] Remove or document unused HostEntry struct #2617
Description
Context
Follow-up from PR #2326 (port node launcher to Rust). Tracked in #2598.
Problem
HostEntry in crates/tee-launcher/src/types.rs (line 74) is defined and has tests but does not appear in any function signatures or runtime code paths. It may be dead code or intended for future use.
Action
Either:
- Remove it if unused, or
- Add a comment explaining its intended purpose and where it will be used
