fix(platform): resolve final lifetime errors in linux_ipc.rs

Fixed E0597 lifetime errors by using static string literals instead of
format! strings in error handling:
- Lines 78-80: bind socket error handling
- Lines 97-99: connect socket error handling

This should resolve the remaining compilation errors blocking CI.
