fix(platform): resolve remaining lifetime errors in random.rs and IPC

Fixed lifetime issues in error handling by using factory methods:
- Used Error::system_io_error() instead of Error::new() with local strings
- Fixed E0597 and E0716 errors in random.rs:90 and linux_ipc.rs:78,95
- Used static string literals to avoid borrowed value lifetime issues

This completes the fix for all compilation errors blocking CI builds.

Closes #99
