no_illegal_windows_names

Reject path components Windows can’t represent:

• Reserved device names (CON, PRN, AUX, NUL, COM1–COM9, LPT1–LPT9) — case-insensitive, regardless of extension. con.txt fails; COM10 and confused correctly pass.
• Trailing dots (foo.) or trailing spaces (foo ) — Windows silently strips these on checkout.
• Reserved chars: <, >, :, ", |, ?, *.
