feat(repl): show messages printed via `TRACE_PRINT_LN`

These are triggered for instance by `println` calls in a Rust program and therefore they should be shown in the **REPL**.

Look for TRACE_PRINT_LN usage in the codebase, likely in the REPL or debugger output handling. Examine how the REPL currently captures and displays output. The change involves modifying the REPL to intercept and show these printed messages. Test by running a Miden program with println statements and verifying they appear in the REPL.
