The POP3 TOP command is unsupported and returns -ERR. Many mail clients issue TOP (header + N body lines) before RETR for previews and header sync.

Fix:

Implement TOP : return the headers plus the first n lines of the body, dot-stuffed and CRLF-terminated (see the RETR dot-stuffing fix).
Advertise via CAPA if/when CAPA is added.

Acceptance:

TOP returns headers plus the requested number of body lines, correctly terminated.
