fix: handle surrogate encoding errors in show_messages on Windows

[ThanhNguyxn]

Summary

Fixes #3844

Emoji characters pasted from Windows clipboard can contain invalid surrogate pairs that cause UnicodeEncodeError: 'utf-8' codec can't encode characters ... surrogates not allowed when printing to the console in verbose mode (-v).

Root Cause

In utils.py line 139, print(formatted_output) directly prints the message content. When the content contains surrogate characters from emoji input, Python's print() fails with UnicodeEncodeError.

Fix

Added try/except around print() in show_messages() to catch UnicodeEncodeError and fall back to encoding with surrogatepass error handler, then decoding with replace to substitute problematic characters:

try:
    print(formatted_output)
except UnicodeEncodeError:
    safe_output = formatted_output.encode("utf-8", errors="surrogatepass").decode(
        "utf-8", errors="replace"
    )
    print(safe_output)

This prevents the crash while still displaying readable output.
