fix(pwndbg): separate the words in the debugger-context limit message (#5372)

The 64 MiB reply-budget refusal rendered as "exceeds64 MiB" because the
message word and the limit were joined. The pwntools sibling names the
same budget as "exceeds the 64 MiB reply budget"; use that wording.

The output-limit path had no producer regression, so the pwndbg suite
gains one that drives the real 64 MiB boundary, and the suite is now part
of test:python instead of running only when invoked by hand.
