Seeded pseudo-random input, biased towards each parser's control bytes,
is fed to the IRC line parser and state machine (plus mIRC formatting),
Telnet IAC negotiation, VNC framebuffer updates (including ZRLE behind a
real zlib stream, with a check that the decoders are actually reached),
~/.ssh/config parsing and the update manifest. None panic, and Telnet's
pending buffer stays bounded.
These run on stable in every CI run; they are not coverage-guided, so a
cargo-fuzz setup (nightly) remains a possible follow-up.
